§ 87.529 Frequencies. Prior to submitting an application,

each applicant must notify the applica-ble FAA Regional Frequency Manage-ment Office. Each application must be accompanied by a statement showing the name of the FAA Regional Office and date notified. The Commission will assign the frequency. Normally, fre-quencies available for air traffic con-trol operations set forth in subpart E will be assigned to an AWOS, ASOS, or to an ATIS. When a licensee has en-tered into an agreement with the FAA to operate the same station as both an AWOS and as an ATIS, or as an ASOS and an ATIS, the same frequency will be used in both modes of operation.

public communications facilities. Enti-ties not meeting these eligibility cri-teria may also be licensed in the Public Safety Radio Pool solely to provide service to eligibles on one-way paging- only frequencies below 800 MHz, i.e., those frequencies with the assignment limitations appearing at § 90.20(d)(13) or (d)(60). Private carrier systems licensed on other channels prior to June 1, 1990, may continue to provide radio commu-nications service to eligibles. Rules as to eligibility for licensing, frequencies available, permissible communications and classes and number of stations, and any special requirements are set forth in the following sections.

§ 90.16 Public Safety National Plan. The Commission has established a

National Plan which specifies special policies and procedures governing the Public Safety Pool (formally Public Safety Radio Services and the Special Emergency Radio Service). The Na-tional Plan is contained in the Report and Order in General Docket No. 87–112. The principal spectrum resource for the National Plan is the 806–809 MHz and the 851–854 MHz bands at locations farther then 110 km (68.4 miles) from the U.S./Mexico border and 140 km (87 miles) from the U.S./Canadian border (‘‘border regions’’). In the border re-gions, the principal spectrum for the National Plan may be different. The National plan establishes planning re-gions covering all parts of the United States, Puerto Rico, and the U.S. Vir-gin Islands. No assignments will be made in the spectrum designated for the National Plan until a regional plan for the area has been accepted by the Commission.

47 CFR Ch. I (10–1–10 Edition) § 90.20

(g) Former public correspondence work-ing channel in the maritime VHF (156–162 MHz) band allocated for public safety use in 33 inland Economic Areas. (1) We de-fine service areas in the marine VHF (156–162 MHz) band by forty-two geo-graphic areas called VHF Public Coast Service Areas (VPCSAs). See § 80.371(c)(1)(ii) of this chapter (Public correspondence frequencies). VPCSAs are based on, and composed of one or more of, the U.S. Department of Com-merce’s 172 Economic Areas (EAs). See 60 Fed Reg. 13114 (Mar. 10, 1995). You may inspect and copy maps of the EAs and VPCSAs at the FCC Reference Cen-ter, Room CY A–257, 445 12th St., SW., Washington, DC 20554. These maps and data are also available on the FCC website at http://www.fcc.gov/oet/info/ maps/areas/. We number public cor-respondence channels in the maritime VHF (156–162 MHz) band as channels 24 to 28 and channels 84 to 88. Each chan-nel number represents a channel pair. See § 80.371(c) of this chapter.

(2) In VHF Public Coast Service Areas (VPCSAs) 10–42, the duplex chan-nel pair 157.250 MHz/161.850 MHz (VHF Maritime Channel 25) is allocated for public safety use by entities eligible for licensing under paragraph (a) of this section, and is designated pri-marily for the purpose of interoper-ability communications. See 47 CFR 80.371(c)(1)(ii) for the definitions of VPCSAs.

(i) The channel pair 157.250 MHz/ 161.850 MHz was formerly allocated and assigned (under § 80.371(c) (1997) of this chapter) as a public correspondence working channel in the maritime VHF 156–162 MHz band, and was also shared (under former § 90.283 (1997) of this chapter) with private land mobile sta-tions, including grandfathered public safety licensees. Thus, there are grand-fathered licensees nationwide (mari-time and private land mobile radio sta-tions, including by rule waiver) oper-ating on this channel both inside and outside of VPCSAs 10–42.

(ii) The channel pairs 157.225 MHz/ 161.825 MHz and 157.275 MHz/161.875 MHz were formerly allocated and assigned under this section as public safety interoperability channels but were re-allocated for assignment as VHF public coast station channels under § 80.371(c)

of this chapter. Public safety oper-ations licensed on these channels as of March 2, 2009 or licensed pursuant to an application filed prior to September 19, 2008, may remain authorized to operate on the channels on a primary basis until March 4, 2024.

(3) All applicants and licensees under this paragraph must comply with the relevant technical sections under this part unless otherwise stated in this paragraph (g) of this section using the following standards and procedures:

(i) Provide evidence of frequency co-ordination in accordance with § 90.175. Public safety coordinators except the Special Emergency Coordinator are certified to coordinate applications for the channel pair 157.250 MHz/161.850 MHz (i.e. , letter symbol PX under paragraph (c)(2) of this section).

(ii) Station power, as measured at the output terminals of the trans-mitter, must not exceed 50 Watts for base stations and 20 Watts for mobile stations, except in accordance with the provisions of paragraph (g)(3)(vi) of this section. Antenna height (HAAT) must not exceed 122 meters (400 feet) for base stations and 4.5 meters (15 feet) for mobile stations, except in ac-cordance with paragraph (g)(3)(vi) of this section. Antenna height (HAAT) must not exceed 122 meters (400 feet) for base stations and 4.5 meters (15 feet) for mobile stations, except in ac-cordance with paragraph (g)(3)(vi) of this section. Such base and mobile channels shall not be operated on board aircraft in flight.

(iii) Frequency protection must be provided to other stations in accord-ance with the following guidelines for each channel and for each area and ad-jacent area:

(A) Protect coast stations licensed prior to July 6, 1998, by the required separations shown in Table C below.

(B) Protect stations described in paragraph (g)(2)(i) of this section, by frequency coordination in accordance § 90.175 of this part.

(C) Protect public safety stations granted under paragraph (g) of this sec-tion by frequency coordination in ac-cordance with § 90.175 of this part.

(D) Where the Public safety designated channel is not a Public safety designated

channel in an adjacent VPCSA: Appli-cants shall engineer base stations such that the maximum signal strength at the boundary of the adjacent VPCSA does not exceed 5dBµV/m.

(iv) The following table, along with the antenna height (HAAT) and power (ERP), must be used to determine the

minimum separation required between proposed base stations and co-channel public coast stations licensed prior to July 6, 1998 under part 80 of this chap-ter. Applicants whose exact ERP or HAAT are not reflected in the table must use the next highest figure shown.

(v) In the event of interference, the Commission may require, without a hearing, licensees of base stations au-thorized under this section that are lo-cated within 241 kilometers (150 miles) of a co-channel public coast, I/LT, or grandfathered public safety station li-censed prior to July 6, 1998, or an inter-national border, to reduce power, de-crease antenna height, and/or install directional antennas.

Mobile stations must be operated only within radio range of their associ-ated base station.

(vi) Applicants seeking to be licensed for stations exceeding the power/an-tenna height limits of the table in paragraph (g)(3)(iv) of this section must request a waiver of that para-graph and must submit with their ap-plication an interference analysis, based upon an appropriate, generally- accepted terrain-based propagation model, that shows that co-channel pro-tected entities, described in paragraph (g)(3)(iii) of this section, would receive the same or greater interference pro-tection than the relevant criteria out-lined in paragraph (g)(3)(iii) of this sec-tion.

(h) Spectrum leasing arrangements. Notwithstanding any other provisions of this section to the contrary, licens-ees in the Public Safety Radio Services (see part 90, subpart B) may enter into spectrum leasing arrangements (see part 1, subpart X of this chapter) with

entities providing communications in support of public safety operations.

Subpart C—Industrial/Business Radio Pool


§ 90.31 Scope. The Industrial/Business Radio Pool

covers the licensing of the radio com-munications of entities engaged in commercial activities, engaged in cler-gy activities, operating educational, philanthropic, or ecclesiastical institu-tions, or operating hospitals, clinics, or medical associations. Rules as to eligi-bility for licensing, frequencies avail-able, permissible communications and classes and number of stations, and any special requirements are set forth in the following sections.

§ 90.33 General eligibility. (a) In addition to the eligibility

shown in the Industrial/Business Pool, eligibility is also provided for any cor-poration proposing to furnish nonprofit radiocommunication service to its par-ent corporation, to another subsidiary of the same parent, or to its own sub-sidiary. This corporate eligibility is not subject to the cooperative use pro-vision of § 90.179.

(b) Eligibility is also provided for a nonprofit corporation or association that is organized for the purpose of fur-nishing a radiocommunications service to persons who meet the eligibility re-quirements of the Industrial/Business

Pool. Such use is subject to the cooper-ative use provisions of § 90.179.

§ 90.35 Industrial/Business Pool. (a) Eligibility. Persons primarily en-

gaged in any of the following activities are eligible to hold authorizations in the Industrial/Business Pool to provide commercial mobile radio service as de-fined in part 20 of this chapter or to op-erate stations for transmission of com-munications necessary to such activi-ties of the licensee:

(1) The operation of a commercial ac-tivity;

(2) The operation of educational, philanthropic, or ecclesiastical institu-tions;

(3) Clergy activities; or (4) The operation of hospitals, clinics,

or medical associations. (5) Public Safety Pool eligibles are

eligible for Industrial/Business Pool spectrum only to The extent that they are engaged in activities listed in para-graphs (a)(1) through (4) of this section. Industrial/Business Pool spectrum many not be utilized for the purposes set forth in § 90.20(a).

(b) Industrial/Business Pool frequencies. (1) The following table indicates fre-quencies available for assignment to Industrial/Business Pool stations, to-gether with the class of station(s) to which they are normally assigned, the specific assignment limitations which are explained in paragraph (b) of this section, and the certified frequency co-ordinator for each frequency:

(2) Unless otherwise specified, coordi-nation of frequencies in the Industrial/ Business pool must be done in accord-ance with the following:

(i) Unless specified elsewhere in this part, frequencies without any coordi-nator specified in the Coordinator col-umn of paragraph (b)(3) of this section may be coordinated by any frequency coordinator certified in the Industrial/ Business Pool.

(ii) A letter symbol in the Coordi-nator column of the frequency table in paragraph (b)(3) of this section des-ignates the mandatory certified fre-quency coordinator for the associated frequency in the table. However, any coordinator certified in the Industrial/ Business Pool may coordinate applica-tions on such frequencies provided the

(c) Explanation of assignment limita-tions appearing in the frequency table of paragraph (b) of this section:

(1) This frequency band is shared with and stations operating in this fre-quency band in this service are on a secondary basis to stations licensed in the Maritime Mobile Service.

(2) This frequency band is shared with and stations operating in this fre-quency band in this service are on a secondary basis to the LORAN Naviga-tion System; all operations are limited to radiolocation land stations in ac-cordance with footnote US104, § 2.106 of this chapter.

(3) [Reserved] (4) The non-Federal Government

radiolocation service in this band is on a secondary basis to stations in the aeronautical radionavigation service operating on 1708 kHz.

(5) Station assignments on fre-quencies in this band will be made sub-ject to the conditions that the max-imum output power shall not exceed 375 watts and the maximum authorized bandwidth shall not exceed 2 kHz.

(6) Because of the operation of sta-tions having priority on the same or adjacent frequencies in this or in other

countries, frequency assignments in this band may either be unavailable or may be subject to certain technical or operational limitations. Therefore, ap-plications for frequency assignments in this band shall include information concerning the transmitter output power, the type and directional charac-teristics of the antenna and the min-imum hours of operation (GMT).

(7) [Reserved] (8) Frequencies in this band may only

be assigned to radiolocation stations which are also assigned frequencies in the 1605–1800 kHz band, provided the use of frequencies in this band is nec-essary for the proper functioning of the particular radiolocation system. Oper-ations in this band are on a secondary basis to stations operating in accord-ance with the Commission’s table of frequency allocations contained in § 2.106 of this chapter.

(9) This band is allocated to the Radiolocation Service on a secondary basis to other fixed or mobile services and must accept any harmful inter-ference that may be experienced from such services or from the industrial, scientific, and medical (ISM) equip-ment operating in accordance with part 18 of this chapter. In the 2483.5– 2500 MHz band, no applications for new or modification to existing stations to increase the number of transmitters will be accepted. Existing licensees as of July 25, 1985, or on a subsequent date following as a result of submitting an application for license on or before July 25, 1985, are grandfathered and their operation is co-primary with the Radiodetermination Satellite Service.

(10) Speed measuring devices will not be authorized in this band.

(11) This frequency band is shared with and is on a secondary basis to the Maritime Radionavigation Stations (part 80) and to the Government Radio-location Service.

(part 87) and to the Government Radio-location Service.

(15) The non-Government Radio-location Service in this band is sec-ondary to the Maritime Radio-navigation Stations (part 80), the Aero-nautical Radionavigation Service (part 87) and the Government Radiolocation Service.

(16) This frequency band is shared with and is on a secondary basis to the Maritime Radionavigation Stations (part 80) and the Government Meteoro-logical Aids Service.

(17) Operation in this frequency band is on a secondary basis to airborne Doppler radars at 8800 MHz.

(18) Radiolocation installations will be coordinated with the Government Meteorological Aids Service, and inso-far as practicable, will be adjusted to meet the needs of that service.

(19) Operations in this band are on a secondary basis to the Amateur Radio Service (part 97). Pulsed emissions are prohibited.

(20) This band is restricted to radio-location systems using type N0N emis-sion with a power not to exceed 40 watts into the antenna.

(21) Non-Government radiolocation stations in the band are secondary to the Government Radiolocation Service, the Amateur Radio Service and the Amateur-Satellite Service. Pulse-rang-ing radiolocation stations in this band may be authorized along the shorelines of Alaska and the contiguous 48 states. Radiolocation stations using spread spectrum techniques may be author-ized in the band 420–435 MHz for oper-ation within the contiguous 48 states and Alaska. Also, stations using spread spectrum techniques shall be limited to a maximum output power of 50 watts, shall be subject to the applica-ble technical standards in § 90.209 until such time as more definitive standards are adopted by the Commission and shall identify in accordance with § 90.425(c)(2). Authorizations will be granted on a case-by-case basis; how-ever, operations proposed to be located within the zones set forth in footnote US217, § 2.106 of this chapter should not expect to be accommodated.

(22) For frequencies 2455 MHz, 10,525 MHz, and 24,125 MHz, only unmodulated, continuous wave (NON)

emission shall be employed. The fre-quency 24.10 GHz, and frequencies in the 24.20–24.25 GHz band may use NON emission along with an ancillary FM digital emission. The frequency 24.10 GHz will be used for the purpose of alerting motorists of hazardous driving conditions and the presence of emer-gency vehicles. Equipment operating on 24.10 GHz must keep the deviation of the FM digital signal within ±5 MHz. Equipment operating on this frequency must have a frequency stability of at least 2000 ppm and is exempt from the requirements of §§ 90.403(c), 90.403(f), and 90.429 of this part.

(23) Devices designed to operate as field disturbance sensors on fre-quencies between 2450 and 2500 MHz with a field strength equal to or less than 50,000 microvolts per meter at 30 meters, on a fundamental frequency, will not be licensed or certificated for use under this part. Such equipment must comply with the requirements for field disturbance sensors as set forth in part 15 of this chapter.

(24) Devices designed to operate as field disturbance sensors on fre-quencies between 10,500 and 10,550 MHz and between 24,050 and 24,250 MHz, with field strength equal to or less than 250,000 microvolts per meter at 30 me-ters, on the fundamental frequency, will not be licensed or certificated for use under this part. Such equipment must comply with the requirements for field disturbance sensors as set forth in part 15 of this chapter.

(25) Station assignments on fre-quencies in this band will be made sub-ject to the conditions that the max-imum output power shall not exceed 375 watts and the maximum authorized bandwidth shall not exceed 1.0 kHz.

(26) Each frequency assignment in this band is on an exclusive basis with-in the primary service area to which assigned. The primary service area is the area where the signal intensities are adequate for radiolocation purposes from all stations in the radiolocation system of which the station in question is a part; that is, the primary service area of the station coincides with the primary service area of the system. The normal minimum geographical separation between stations of dif-ferent licensees shall be at least 1931

km (1200 miles) when the stations are operated on the same frequency or on different frequencies separated by less than 1.0 kHz. Where geographical sepa-ration of less than 1931 km (1200 miles) is requested under these cir-cumstances, it must be shown that the desired separation will result in a pro-tection ratio of at least 20 decibels throughout the primary service area of other stations.

(27) Notwithstanding the bandwidth limitations otherwise set forth in this section of the rules, wideband systems desiring to operate in this band may use such bandwidth as is necessary for proper operation of the system pro-vided that the field strength does not exceed 120 microvolts per meter per square root Hertz (120 uv/m/Hz1⁄2) at 1.6 km (1 mile). Such wideband operations shall be authorized on a secondary basis to stations operating within oth-erwise applicable technical standards. Applications for wideband systems in this band will be accepted beginning December 15, 1985.

(28) Until July 1, 1988, this band will be available only for licensees of exist-ing systems operating in the 1605–1705 kHz portion of the 1605–1715 kHz band requesting modification of their au-thorizations to change frequencies to this band and for licensees of wideband systems. On July 1, 1988, requests for new station authorizations in this band will be accepted and, if necessary, will be subject to the random selection pro-cedures outlined in § 1.972 of the Com-mission’s Rules.

(29) This frequency band is shared with and is on secondary basis to the Fixed-Satellite Service and to the Gov-ernment’s Radiolocation, Space Re-search and Earth Exploration-Satellite Services. After January 1, 2000, the Government’s Space Research and Earth Exploration-Satellite Services shall operate on a co-equal secondary basis with the non-Government Radio-location Service, except that grand-fathered space stations in the Tracking and Data Relay Satellite System shall continue to be protected from harmful interference.

(d) Other additional frequencies avail-able. Radiolocation stations in this service may be authorized, on request, to use frequencies allocated exclusively

to Federal Government stations, in those instances where the Commission finds, after consultation with the ap-propriate Government agency or agen-cies, that such assignment is necessary or required for coordination with Gov-ernment activities.

§ 90.155 Time in which station must be placed in operation.

(a) All stations authorized under this part, except as provided in §§ 90.528, 90.529, 90.629, 90.631(f), 90.665, 90.685, and 90.1209, must be placed in operation within twelve (12) months from the date of grant or the authorization can-cels automatically and must be re-turned to the Commission.

(b) A local government entity in the Public Safety Pool, applying for any frequency in this part, may also seek extended implementation authoriza-tion pursuant to § 90.629.

(c) For purposes of this section, a base station is not considered to be placed in operation unless at least one associated mobile station is also placed in operation. See also §§ 90.633(d) and 90.631(f).

47 CFR Ch. I (10–1–10 Edition) § 90.157

§ 90.353, must construct and place in op-eration a sufficient number of base sta-tions that utilize multilateration tech-nology (see paragraph (e) of this sec-tion) to provide multilateration loca-tion service to one-third of the EA’s population within five years of initial license grant, and two-thirds of the population within ten years. Licensees may, in the alternative, provide sub-stantial service to their licensed area within the appropriate five- and ten- year benchmarks. In demonstrating compliance with the construction and coverage requirements, the Commis-sion will allow licensees to individually determine an appropriate field strength for reliable service, taking into ac-count the technologies employed in their system design and other relevant technical factors. At the five- and ten- year benchmarks, licensees will be re-quired to file a map and FCC Form 601 showing compliance with the coverage requirements (see § 1.946 of this chap-ter).

(e) A multilateration LMS station will be considered constructed and placed in operation if it is built in ac-cordance with its authorized param-eters and is regularly interacting with one or more other stations to provide location service, using multilateration technology, to one or more mobile units. Specifically, LMS multilateration stations will only be considered constructed and placed in operation if they are part of a system that can interrogate a mobile, receive the response at 3 or more sites, com-pute the location from the time of ar-rival of the responses and transmit the location either back to the mobile or to a subscriber’s fixed site.

(f) For purposes of this section, a sta-tion licensed to provide commercial mobile radio service is not considered to have commenced service unless it provides service to at least one unaf-filiated party.

(g) Application for extension of time to commence service may be made on FCC Form 601. Extensions of time must be filed prior to the expiration of the construction period. Extensions will be granted only if the licensee shows that the failure to commence service is due to causes beyond its control. No exten-sions will be granted for delays caused

by lack of financing, lack of site avail-ability, for the assignment or transfer of control of an authorization, or for failure to timely order equipment. If the licensee orders equipment within 90 days of the license grant, a presump-tion of due diligence is created.

(h) An application for modification of an authorization (under construction) at the existing location does not ex-tend the initial construction period. If additional time to commence service is required, a request for such additional time must be submitted on FCC Form 601, either separately or in conjunction with the submission of the FCC Form 601 requesting modification.

(i) DSRCS Roadside Units (RSUs) in the 5850–5925 MHz band must be placed in operation within 12 months from the date of registration (see § 90.375) or the authority to operate the RSUs cancels automatically (see § 1.955 of this chap-ter). Such registration date(s) do not change the overall renewal period of the single license. Licensees must no-tify the Commission in accordance with § 1.946 of this chapter when reg-istered units are placed in operation within their construction period.

§ 90.157 Discontinuance of station op-eration.

(a) An authorization shall cancel automatically upon permanent dis-continuance of operations. Unless stat-ed otherwise in this part or in a station authorization, for the purposes of this section, any station which has not op-erated for one year or more is consid-ered to have been permanently discon-tinued.

(b) For DSRCS Roadside Units (RSUs) in the 5850–5925 MHz band, it is the DSRCS licensee’s responsibility to delete from the registration database any RSUs that have been discontinued.

station(s) for a period of up to one hun-dred eighty (180) days after submitting a Form 601 application for a station li-cense in accordance with § 90.127 of this part, provided that all the antennas employed by control stations are 6.1 meters (20 feet) or less above ground or 6.1 meters (20 feet) or less above a man- made structure other than an antenna tower to which it is affixed. When re-quired by § 90.175 of this part, applica-tions must be accompanied by evidence of frequency coordination. The tem-porary operation of stations, other than mobile stations within the Cana-dian coordination zone is limited to stations with a maximum of 5 watts ef-fective radiated power and a maximum antenna height of 6.1 meters (20 ft) above average terrain.

(b) An applicant proposing to operate a new land mobile radio station or modify an existing station below 470 MHz or in the one-way paging 929–930 MHz band (other than a commercial mobile radio service applicant or li-censee on these bands) that is required to submit a frequency recommendation pursuant to paragraphs (b) through (h) of § 90.175 of this part may operate the proposed station during the pendency of its application for a period of up to one hundred eighty (180) days upon the filing of a properly completed formal Form 601 application that complies with § 90.127 of this part if the applica-tion is accompanied by evidence of fre-quency coordination in accordance with § 90.175 of this part and provided that the following conditions are satis-fied:

(1) For applicants proposing to oper-ate below 470 MHz, that the proposed station location is south of Line A or west of Line C as defined in § 90.7; for applicants in the one-way paging 929– 930 MHz band, that the proposed sta-tion location is west of Line C as de-fined in § 90.7.

(2) The proposed antenna structure has been previously studied by the Fed-eral Aviation Administration and de-termined to pose no hazard to aviation safety as required by § 17.4 of the Com-mission’s Rules; or the proposed an-tenna or tower structure does not ex-ceed 6.1 meters (20 feet) above ground level or above an existing man-made structure (other than an antenna struc-

ture), if the antenna or tower has not been previously studied by the Federal Aviation Administration and cleared by the FCC.

(3) The grant of the application does not require a waiver of the Commis-sion’s Rules.

(4) The applicant has determined that the proposed facility will not signifi-cantly affect the environment as de-fined in § 1.1307.

(5) The applicant has determined that the proposed station affords the level of protection to radio quiet zones and radio receiving facilities as specified in § 1.924 of this chapter.

(6) The applicant has submitted an application to the Commission stating the frequency the applicant intends to use and that the frequency coordina-tion requirements specified in § 90.175 for selection and use of this frequency have been met and a minimum of ten business days has passed between sub-mission of the application to the Com-mission and the onset of operation.

(c) An applicant proposing to operate an itinerant station or an applicant seeking the assignment of authoriza-tion or transfer of control of a license for an existing station below 470 MHz or in the 929–930 MHz band (other than a commercial mobile radio service ap-plicant or licensee on these bands) may operate the proposed station during the pendency of the application for a pe-riod not to exceed one hundred eighty (180) days upon the filing of a properly completed formal Form 601 application that complies with § 90.127 of this part. Conditional authority ceases imme-diately if the application is dismissed by the Commission. All other cat-egories of applications listed in § 90.175(i) of this part that do not re-quire evidence of frequency coordina-tion are excluded from the provisions of this section.

(d) Conditional authorization does not prejudice any action the Commis-sion may take on the subject applica-tion. Conditional authority is accepted with the express understanding that such authority may be modified or can-celed by the Commission at any time without hearing if, in the Commis-sion’s discretion, the need for such ac-tion arises. Consistent with § 90.175(g) of this part, the applicant assumes all

SPECIAL RULES GOVERNING FACILITIES USED TO PROVIDE COMMERCIAL MO-BILE RADIO SERVICES

SOURCE: 59 FR 59959, Nov. 21, 1994; 63 FR 68964, Dec. 14, 1998, unless otherwise noted.

NOTE: The following rules (§§ 90.165 through 90.169) govern applications, licensing, and op-eration of radio facilities in the 220–222 MHz (subpart T), Business Radio (subpart D), 929– 930 MHz Paging (subpart P), and Specialized Mobile Radio (subpart S) services that are used to provide commercial mobile radio services (see §§ 20.3 and 20.9 of this chapter). Compliance with the rules relating to appli-cations and licensing of facilities on paging- only channels in the Business Radio Service (see § 90.75(c)(10)) and 929–930 MHz paging channels (see § 90.494(a),(b)) is not required prior to August 10, 1996. Compliance with § 90.168 is also not required prior to August 10, 1996 for reclassified commercial mobile radio service providers who are to be regu-lated as private carriers until August 10, 1996 as provided in the Second Report and Order in GN Docket No. 93–252, 9 FCC Rcd 2348 (1994), paras. 280–284. The licensing and oper-ation of radio facilities in the 220–222 MHz (subpart T), Business Radio (subpart D), 929– 930 MHz Paging (subpart P), and Specialized Mobile Radio (subpart S) services that are used to provide commercial mobile radio services are also subject to rules elsewhere in this part that apply generally to Private Land Mobile Radio Services. In the case of any conflict between rules set forth in §§ 90.165 through 90.169 and other rules in this part, §§ 90.165 through 90.169 apply. 14–23. New

§§ 90.165 through 90.169 are added to subpart G to read as follows:

§ 90.165 Procedures for mutually ex-clusive applications.

Mutually exclusive commercial mo-bile radio service applications are proc-essed in accordance with part 1 of this chapter and with the rules in this sec-tion, except for mutually exclusive ap-plications for licenses in the 220–222 MHz service and the 929–930 MHz Pag-ing service, which are processed in ac-cordance with the rules in subpart P and subpart T of this part.

Two or more pending applications are mutually exclusive if the grant of one application would effectively preclude the grant of one or more of the others under Commission rules governing the services involved.

(a) Separate applications. Any appli-cant that files an application knowing that it will be mutually exclusive with one or more applications should not in-clude in the mutually exclusive appli-cation a request for other channels or facilities that would not, by them-selves, render the application mutually exclusive with those other applica-tions. Instead, the request for such other channels or facilities should be filed in a separate application.

(b) Filing groups. Pending mutually exclusive applications are processed in filing groups. Mutually exclusive appli-cations in a filing group are given con-current consideration. The Commission may dismiss as defective (pursuant to § 1.934 of this chapter) any mutually ex-clusive application(s) whose filing date is outside of the date range for inclu-sion in the filing group. The types of filing groups used in day-to-day appli-cation processing are specified in para-graph (c)(3) of this section. A filing group is one of the following types:

(1) Renewal filing group. A renewal fil-ing group comprises a timely-filed ap-plication for renewal of an authoriza-tion and all timely-filed mutually ex-clusive competing applications (see section 1.949 of this chapter).

(2) Same-day filing group. A same-day filing group comprises all mutually ex-clusive applications whose filing date is the same day, which is normally the filing date of the first-filed applica-tions(s).

(3) Thirty-day notice and cut-off filing group. A 30-day notice and cut-off filing group comprises mutually exclusive applications whose filing date is no later than thirty (30) days after the date of the Public Notice listing the first-filed application(s) (according to the filing dates) as acceptable for fil-ing.

(4) Window filing group. A window fil-ing group comprises mutually exclu-sive applications whose filing date is within an announced filing window. An announced filing window is a period of time between and including two spe-cific dates, which are the first and last dates on which applications (or amend-ments) for a particular purpose may be accepted for filing. In the case of a one- day filing window, the two dates are the same. The dates are made known to the public in advance.

(c) Procedures. Generally, the Com-mission may grant one application in a filing group of mutually exclusive ap-plications and dismiss the other appli-cation(s) in the filing group that are excluded by the grant, pursuant to § 1.935 of this chapter.

(1) Selection methods. In selecting the application to grant, the Commission may use competitive bidding, random selection, or comparative hearings, de-pending on the type of applications in-volved.

(2) Dismissal of applications. The Com-mission may dismiss any application in a filing group that is defective or oth-erwise subject to dismissal under § 1.934 of this chapter, either before or after employing selection procedures.

(3) Type of filing group used. Except as otherwise provided in this part, the type of filing group used in processing of two or more mutually exclusive ap-plications depends on the purpose(s) of the applications.

(i) If one of the mutually exclusive applications is a timely-filed applica-tion for renewal of an authorization, a renewal filing group is used.

(ii) If any mutually exclusive appli-cation filed on the earliest filing date is an application for modification and none of the mutually exclusive applica-tions is a timely-filed application for renewal, a same-day filing group is used.

(iii) If all of the mutually exclusive applications filed on the earliest filing date are applications for initial author-ization, a 30-day notice and cut-off fil-ing group is used.

(4) Disposition. If there is only one ap-plication in any type of filing group, the Commission may grant that appli-cation and dismiss without prejudice any mutually exclusive applications not in the filing group. If there is more than one mutually exclusive applica-tion in a filing group, the Commission disposes of these applications as fol-lows:

(i) Applications in a renewal filing group. All mutually exclusive applica-tions in a renewal filing group are des-ignated for comparative consideration in a hearing.

(ii) Applications in a 30-day notice and cut-off filing group.

(A) If all of the mutually exclusive applications in a 30-day notice and cut- off filing group are applications for ini-tial authorization, the Commission ad-ministers competitive bidding proce-dures in accordance with subpart Q of part 1 of this chapter. After such proce-dures, the application of the successful bidder may be granted and the other applications may be dismissed without prejudice.

(B) If any of the mutually exclusive applications in a 30-day notice and cut- off filing group is an application for modification or an application for fa-cilities, the Commission may attempt to resolve the mutual exclusivity by fa-cilitating a settlement between the ap-plicants. If a settlement is not reached within a reasonable time, the Commis-sion may designate all applications in the filing group for comparative con-sideration in a hearing. In this event, the result of the hearing disposes all of the applications in the filing group.

(iii) Applications in a same-day filing group. If there are two or more mutu-ally exclusive applications in a same- day filing group, the Commission may attempt to resolve the mutual exclu-sivity by facilitating a settlement be-tween the applicants. If a settlement is not reached within a reasonable time, the Commission may designate all ap-plications in the filing group for com-parative consideration in a hearing. In this event, the result of the hearing

disposes all of the applications in the filing group.

(iv) Applications in a window filing group. Applications in a window filing group are processed in accordance with the procedures for a 30-day notice and cut-off filing group in paragraph (c)(4)(ii) of this section.

(d) Terminology. For the purposes of this section, terms have the following meanings:

(1) The ‘‘filing date’’ of an applica-tion is the date on which that applica-tion was received in a condition ac-ceptable for filing or the date on which the most recently filed major amend-ment to that application was received, whichever is later, excluding major amendments in the following cir-cumstances:

(i) The major amendment reflects only a change in ownership or control found by the Commission to be in the public interest;

(ii) The major amendment as re-ceived is defective or otherwise found unacceptable for filing; or

(iii) The application being amended has been designated for hearing and the Commission or the presiding officer ac-cepts the major amendment.

(2) An ‘‘application for initial author-ization’’ is:

(i) Any application requesting an au-thorization for a new system or sta-tion;

(ii) Any application requesting au-thorization for an existing station to operate on an additional channel, un-less the additional channel is for paired two-way radiotelephone operation, is in the same frequency range as the ex-isting channel(s), and will be oper-ationally integrated with the existing channel(s) such as by trunking; or

(iii) any application requesting au-thorization for a new transmitter at a location more than 2 kilometers (1.2 miles) from any existing transmitters of the applicant licensee on the re-quested channel or channel block.

(2) Any licensee who has filed such information with the EEOC may file a notification of such filing with the Commission in lieu of a report.

(d) Complaints of violations of Equal Employment Programs. Complaints al-leging employment discrimination against a common carrier licensee are considered by the Commission in the following manner:

(1) If a complaint raising an issue of discrimination is received against a li-censee who is within the jurisdiction of the EEOC, it is submitted to that agen-cy. The Commission maintains a liai-son with that agency that keeps the Commission informed of the disposi-tion of complaints filed against com-mon carrier licensees.

(2) Complaints alleging employment discrimination against a common car-rier licensee who does not fall under the jurisdiction of the EEOC but is cov-ered by appropriate enforceable State law, to which penalties apply, may be submitted by the Commission to the respective State agency.

(3) Complaints alleging employment discrimination against a common car-rier licensee who does not fall under the jurisdiction of the EEOC or an ap-

propriate State law, are accorded ap-propriate treatment by the Commis-sion.

(4) The Commission will consult with the EEOC on all matters relating to the evaluation and determination of compliance by the common carrier li-censees with the principles of equal employment as set forth herein.

(5) Complaints indicating a general pattern of disregard of equal employ-ment practices which are received against a licensee that is required to file an employment report to the Com-mission under § 1.815(a) of this chapter are investigated by the Commission.

authorization. If the conditions stated in this section are not met, applicants must not begin to construct facilities.

(a) When applicants may begin con-struction. An applicant may begin con-struction of a facility thirty-five (35) days after the date of the Public Notice listing the application for that facility as acceptable for filing.

(b) Notification to stop. If the Commis-sion for any reason determines that construction should not be started or should be stopped while an application is pending, and so notifies the appli-cant, orally (followed by written con-firmation) or in writing, the applicant must not begin construction or, if con-struction has begun, must stop con-struction immediately.

(c) Assumption of risk. Applicants that begin construction pursuant to this section before receiving an authoriza-tion do so at their own risk and have no recourse against the United States for any losses resulting from:

(1) Applications that are not granted; (2) Errors or delays in issuing Public

Notices; (3) Having to alter, relocate, or dis-

mantle the facility; or (4) Incurring whatever costs may be

necessary to bring the facility into compliance with applicable laws, or Commission rules and orders.

(d) Conditions. Except as indicated, all pre-grant construction is subject to the following conditions:

(1) The application is not mutually exclusive with any other application;

(2) No petitions to deny the applica-tion have been filed;

(3) The application does not include a request for a waiver of one or more Commission rules;

(4) For any construction or alter-ation that would exceed the require-ments of § 17.7 of this chapter, the li-censee has notified the appropriate Re-gional Office of the Federal Aviation Administration (FAA Form 7460–1), filed a request for antenna height clearance and obstruction marking and lighting specifications (FCC Form 854) with the Commission;

(5) The applicant has indicated in the application that the proposed facility would not have a significant environ-mental effect, in accordance with

§§ 1.1301 through 1.1319 of this chapter; and,

(6) Under applicable international agreements and rules in this part, indi-vidual coordination of the proposed channel assignment(s) with a foreign administration is not required.

Subpart H—Policies Governing the Assignment of Frequencies

§ 90.171 Scope.

This subpart contains detailed infor-mation concerning the policies under which the Commission assigns fre-quencies for the use of licensees under this part, frequency coordination pro-cedures, and procedures under which li-censees may cooperatively share radio facilities.

§ 90.173 Policies governing the assign-ment of frequencies.

(a) Except as indicated in paragraph (j) of this section, the frequencies which ordinarily may be assigned to stations in the services governed by this part are listed in subparts B, C and F of this part. Except as otherwise spe-cifically provided in this part, fre-quencies assigned to land mobile sta-tions are available on a shared basis only and will not be assigned for the exclusive use of any licensee.

(b) All applicants and licensees shall cooperate in the selection and use of frequencies in order to reduce inter-ference and make the most effective use of the authorized facilities. Licens-ees of stations suffering or causing harmful interference are expected to cooperate and resolve this problem by mutually satisfactory arrangements. If the licensees are unable to do so, the Commission may impose restrictions including specifying the transmitter power, antenna height, or area or hours of operation of the stations concerned. Further the use of any frequency at a given geographical location may be de-nied when, in the judgment of the Com-mission, its use in that location is not in the public interest; the use of any frequency may be restricted as to spec-ified geographical areas, maximum power, or such other operating condi-tions, contained in this part or in the station authorization.

47 CFR Ch. I (10–1–10 Edition) § 90.173

(c) Frequencies allocated for Federal Government radio stations under Exec-utive order of the President may be au-thorized for the use of stations in these services upon appropriate showing by the applicant that such assignment is necessary for inter-communication with government stations or required for coordination with activities of the Federal Government, and where the Commission finds, after consultation with the appropriate government agen-cy or agencies, that such assignment is necessary.

(d) The radio facilities authorized under this part are intended for use in connection with and as an adjunct to the primary governmental or business activities of the licensee.

(e) Persons requesting authority to operate in the band 25–50 MHz should recognize that this band is shared with various services in other countries and that harmful interference may be caused by the propagation of signals in this band from distant stations. No protection from such harmful inter-ference generally can be expected.

(f) Applications for stations in the 150–174 MHz and 421–512 MHz bands for operation on frequencies 15 kHz or less removed from existing stations in the same geographic area will be granted based upon a recommendation from the applicable frequency coordinator as specified in §§ 90.20(c)(2) and 90.35(b)(2).

(g) In the states of Alaska and Ha-waii, and in areas outside the conti-nental limits of the United States and the adjacent waters, the frequencies above 150.8 MHz which are listed else-where in this part as available for as-signment to base stations or mobile stations in the Industrial/Business Pool are also available for assignment to operational fixed stations in the Indus-trial/Business Pool on a secondary basis.

(h) In the Public Safety Pool, base stations may be authorized to operate on a secondary basis on frequencies below 450 MHz which are available to mobile stations.

(i) In the 450–470 MHz band, the fre-quencies are ordinarily assigned in pairs, with the mobile station transmit frequency 5 MHz above the paired base station transmit frequency. In the 470– 512 MHz band, the frequencies are ordi-

narily assigned in pairs with the mo-bile station transmit frequency 3 MHz above the paired base station transmit frequency. In the Industrial/Business Pool, in the 150 MHz band, the fre-quencies subject to § 90.35(c)(6) may be assigned in pairs with the separation between base and mobile frequencies being 5.26 MHz. A mobile station may be assigned the frequency which would normally be assigned to a base station for single-frequency operation. How-ever, this single-frequency operation may be subject to interference that would not occur to a two-frequency system.

(j) Frequencies other than those list-ed in subparts B and C of this part may be assigned in the 150–174 MHz, 421–430 MHz, 450–470 MHz, and 470–512 MHz bands, provided the following condi-tions are met:

(1) Such applications must be accom-panied by a showing of frequency co-ordination in accordance with the re-quirements of § 90.175;

(2) The frequencies must not be avail-able in any other rule part of this chap-ter; and

(3) The authorized bandwidth of any system operating in accordance with this paragraph must not overlap spec-trum available in other rule parts of this chapter unless that spectrum is also allocated in part 90.

(k) This paragraph is only applicable to entities with Finder’s Preference re-quests pending before the Commission as of July 29, 1998. Notwithstanding any other provisions of this part, any eligible person shall be given a disposi-tive preference for a channel assign-ment on an exclusive basis in the 220– 222 MHz, 470–512 MHz, and 800/900 MHz (except on frequencies designated ex-clusively for SMR service) bands by submitting information that leads to the recovery of channels in these bands. Recovery of such channels must result from information provided re-garding the failure of existing licensees to comply with the provisions of § 90.155, § 90.157, § 90.629, § 90.631 (e) or (f), or § 90.633 (c) or (d).

(l) In the 150–174 MHz band, except where otherwise specifically provided, authorizations for frequencies that were available prior to August 18, 1995 will be granted with channel

bandwidths of 25 kHz or less. Author-izations for all other frequencies in this band will be granted with channel bandwidths of 12.5 kHz or less (i.e., in the Public Safety Pool, frequencies subject to §§ 90.20 (d)(27) and (d)(44), and in the Industrial/Business Pool, fre-quencies subject to §§ 90.35 (c)(30) and (c)(33)).

(m) In the 421–512 MHz band, except where otherwise specifically provided, authorizations for frequencies that were available prior to August 18, 1995 will be granted with channel bandwidths of 25 kHz or less. New au-thorizations for frequencies 12.5 kHz re-moved from these frequencies will be made for channel bandwidths of 12.5 kHz or less (i.e., in the Public Safety Pool, frequencies subject to § 90.20(d)(27) and in the Industrial/Busi-ness Pool, frequencies subject to § 90.35(c)(30)). Authorizations for fre-quencies 6.25 kHz removed from these frequencies will be granted with chan-nel bandwidths of 6.25 kHz or less (i.e., in the Public Safety Pool, frequencies subject to § 90.20(d)(44), and in the In-dustrial/Business Pool, frequencies sub-ject to § 90.35(c)(33)).

(n) Any recovered channels in the 800 MHz SMR service will revert automati-cally to the holder of the EA license within which such channels are in-cluded. If there is no EA licensee for re-covered channels, such channels will be retained by the Commission for future licensing.

(Secs. 4, 303, 307, 48 Stat., as amended, 1066, 1082, 1083; 47 U.S.C. 154, 303, 307)

§ 90.175 Frequency coordinator re-quirements.

Except for applications listed in paragraph (j) of this section, each ap-plication for a new frequency assign-ment, for a change in existing facilities as listed in § 90.135(a), or for operation at temporary locations in accordance with § 90.137 must include a showing of frequency coordination as set forth fur-ther.

(a) Frequency coordinators may re-quest, and applicants are required to provide, all appropriate technical in-formation, system requirements, and justification for requested station pa-rameters when such information is nec-essary to identify and recommend the most appropriate frequency. Addition-ally, applicants bear the burden of pro-ceeding and the burden of proof in re-questing the Commission to overturn a coordinator’s recommendation.

(b) For frequencies between 25 and 470 MHz: (1) A statement is required from the applicable frequency coordinator as specified in §§ 90.20(c)(2) and 90.35(b) recommending the most appropriate frequency. In addition, for frequencies above 150 MHz, if the interference con-tour of a proposed station would over-lap the service contour of a station on a frequency formerly shared prior to radio service consolidation by licensees in the Manufacturers Radio Service, the Forest Products Radio Service, the Power Radio Service, the Petroleum Radio Service, the Motor Carrier Radio Service, the Railroad Radio Service, the Telephone Maintenance Radio Service or the Automobile Emergency Radio Service, the written concurrence of the coordinator for the industry-spe-cific service, or the written concur-rence of the licensee itself, must be ob-tained. Requests for concurrence must be responded to within 20 days of re-ceipt of the request. The written re-quest for concurrence shall advise the receiving party of the maximum 20 day response period. The coordinator’s rec-ommendation may include comments on technical factors such as power, an-tenna height and gain, terrain and other factors which may serve to mini-mize potential interference. In addi-tion:

(2) On frequencies designated for co-ordination or concurrence by a specific frequency coordinator as specified in §§ 90.20(c)(3) and 90.35(b), the applicable frequency coordinator shall provide a written supporting statement in in-stances in which coordination or con-currence is denied. The supporting statement shall contain sufficient de-tail to permit discernment of the tech-nical basis for the denial of concur-rence. Concurrence may be denied only

when a grant of the underlying applica-tion would have a demonstrable, mate-rial, adverse effect on safety.

(3) In instances in which a frequency coordinator determines that an appli-cant’s requested frequency or the most appropriate frequency is one des-ignated for coordination or concur-rence by a specific frequency coordi-nator as specified in § 90.20(c)(3) or § 90.35(b), that frequency coordinator may forward the application directly to the appropriate frequency coordi-nator. A frequency coordinator may only forward an application as speci-fied above if consent is received from the applicant.

(c) For frequencies above 800 MHz: When frequencies are shared by more than one service, concurrence must be obtained from the other applicable cer-tified coordinators.

(d) For frequencies in the 450–470 MHz band: When used for secondary fixed operations, frequencies shall be as-signed and coordinated pursuant to § 90.261.

(e) For frequencies between 470–512 MHz, 769–775/799–805 MHz, 806–824/851–869 MHz and 896–901/935–940 MHz: A rec-ommendation of the specific fre-quencies that are available for assign-ment in accordance with the loading standards and mileage separations ap-plicable to the specific radio service, frequency pool, or category of user in-volved is required from an applicable frequency coordinator.

(f) For frequencies in the 929–930 MHz band listed in paragraph (b) of § 90.494: A statement is required from the coordi-nator recommending the most appro-priate frequency.

(g) For frequencies between 1427–1432 MHz: A statement is required from the coordinator recommending the most appropriate frequency, operating power and area of operation in accordance with the requirements of § 90.259(b).

(h) Any recommendation submitted in accordance with paragraphs (a), (c), (d), or (e) of this section is advisory in character and is not an assurance that the Commission will grant a license for operation on that frequency. Therefore, applicants are strongly advised not to purchase radio equipment operating on specific frequencies until a valid au-

thorization has been obtained from the Commission.

(i) Applications for facilities near the Canadian border north of line A or east of line C in Alaska may require coordi-nation with the Canadian government. See § 1.928 of this chapter.

(j) The following applications need not be accompanied by evidence of fre-quency coordination:

(1) Applications for frequencies below 25 MHz.

(2) Applications for a Federal Govern-ment frequency.

(3) Applications for frequencies in the 72–76 MHz band except for mobile fre-quencies subject to § 90.35(c)(77).

EFFECTIVE DATE NOTE: At 72 FR 48859, Aug. 24, 2007, § 90.176 was amended by revising the section heading and heading to paragraph (c). This text contains information collec-tion and recordkeeping requirements and will not become effective until approval has been given by the Office of Management and Budget.

§ 90.179 Shared use of radio stations. Licensees of radio stations author-

ized under this rule part may share the use of their facilities. A station is shared when persons not licensed for the station control the station for their own purposes pursuant to the li-censee’s authorization. Shared use of a radio station may be either on a non- profit cost shared basis or on a for- profit private carrier basis. Shared use of an authorized station is subject to the following conditions and limita-tions:

(a) Persons may share a radio station only on frequencies for which they would be eligible for a separate author-ization.

(b) The licensee of the shared radio station is responsible for assuring that the authorized facility is used only by persons and only for purposes con-sistent with the requirements of this rule part.

(c) Participants in the sharing ar-rangement may obtain a license for their own mobile units (including con-trol points and/or control stations for control of the shared facility), or they may use mobile stations, and control stations or control points authorized to the licensee.

(d) If the licensee shares the land sta-tion on a non-profit, cost shared basis to the licensee, this shared use must be

pursuant to a written agreement be-tween the licensee and each participant which sets out (1) the method of oper-ation, (2) the components of the system which are covered by the sharing ar-rangements, (3) the method by which costs are to be apportioned, and (4) ac-knowledgement that all shared trans-mitter use must be subject to the li-censee’s control. These agreements must be kept as part of the station records.

(e) If the land station which is being shared is interconnected with the pub-lic switched telephone network, the provisions of § 90.477 et seq. apply.

(f) Above 800 MHz, shared use on a for-profit private carrier basis is per-mitted only by SMR, Private Carrier Paging, LMS, and DSRCS licensees. See subparts M, P, and S of this part.

(g) Notwithstanding paragraph (a) of this section, licensees authorized to op-erate radio systems on Public Safety Pool frequencies designated in § 90.20 may share their facilities with Federal Government entities on a non-profit, cost-shared basis. Such a sharing ar-rangement is subject to the provisions of paragraphs (b), (d), and (e) of this section, and § 2.103(c) concerning ap-proval of the Public Safety Broadband Licensee for Federal operations in the 763–768 MHz and 793–798 MHz bands. State governments authorized to oper-ate radio systems under § 90.529 may share the use of their systems (for pub-lic safety services not made commer-cially available to the public) with any entity that would be eligible for licens-ing under § 90.523 and Federal Govern-ment entities.

(h) Notwithstanding paragraph (a) of this section, licensees authorized to op-erate radio systems on Industrial/Busi-ness Pool frequencies designated in § 90.35 may share their facilities with Public Safety Pool entities designated in § 90.20 and with Federal Government entities on a non-profit, cost-shared basis. Such a sharing arrangement is subject to the provisions of paragraphs (b), (d), and (e) of this section.

(i) The provisions of this section do not apply to licensees authorized to provide commercial mobile radio serv-ice under this part, including licensees authorized to use channels transferred or assigned pursuant to § 90.621(e)(2).

§ 90.187 Trunking in the bands be-tween 150 and 512 MHz.

(a) Applicants for trunked systems operating on frequencies between 150 and 512 MHz (except 220–222 MHz) must indicate on their applications (class of station code, instructions for FCC Form 601) that their system will be trunked. Licensees of stations that are not trunked, may trunk their systems only after modifying their license (see § 1.927 of this chapter).

(b) Trunked systems operating under this section must employ equipment that prevents transmission on a trunked frequency if a signal from an-other system is present on that fre-quency. The level of monitoring must be sufficient to avoid causing harmful interference to other systems. How-ever, this monitoring requirement does not apply if the conditions in para-

graph (b)(1) or (b)(2) of this section, are met:

(1) Where applicants for or licensees operating in the 470–512 MHz band meet the loading requirements of § 90.313 and have exclusive use of their frequencies in their service area.

(2) On frequencies where an applicant or licensee does not have an exclusive service area provided that all fre-quency coordination requirements are complied with and written consent is obtained from affected licensees using either the procedure set forth in para-graphs (b)(2)(i) and (b)(2)(ii) of this sec-tion (mileage separation) or the proce-dure set forth in paragraph (b)(2)(iii) of this section (protected contours).

(i) Affected licensees for the purposes of this section are licensees of stations that have assigned frequencies (base and mobile) that are 15 kHz or less re-moved from proposed stations that will operate with a 25 kHz channel band-width; stations that have assigned fre-quencies (base and mobile) that are 7.5 kHz or less removed from proposed sta-tions that will operate with a 12.5 kHz bandwidth; or stations that have as-signed frequencies (base and mobile) 3.75 kHz or less removed from proposed stations that will operate with a 6.25 kHz bandwidth.

(ii) Where such stations’ service areas (37 dBu contour for stations in the 150–174 MHz band and 39 dBu con-tour for stations in the 421–512 MHz bands; see § 90.205) overlap a circle with radius 113 km (70 mi.) from the pro-posed base station.

(iii) In lieu of the mileage separation procedure set forth in paragraphs (b)(2)(i) and (b)(2)(ii) of this section, ap-plicants for trunked facilities may ob-tain consent only from stations that would be subjected to objectionable in-terference from the trunked facilities. Objectionable interference will be con-sidered to exist when the interference contour (19 dBu for VHF stations, 21 dBu for UHF stations) of a proposed trunked station would intersect the service contour (37 dBu for VHF sta-tions, 39 dBu for UHF stations) of an existing station. The existing stations that must be considered in a contour overlap analysis are a function of the channel bandwidth of the proposed trunked station, as follows:

(B) For trunked stations proposing 12.5 kHz channel bandwidth: Existing co-channel stations and existing sta-tions that have an operating frequency 7.5 kHz or less from the proposed trunked station.

(C) For trunked stations proposing 6.25 kHz channel bandwidth: Existing co-channel stations and existing sta-tions that have an operating frequency 3.75 kHz or less from the proposed trunked station.

(iv) The calculation of service and in-terference contours referenced in para-graph (b)(2)(iii) of this section shall be done using generally accepted engi-neering practices and standards which, for purposes of this section, shall pre-sumptively be the practices and stand-ards agreed to by a consensus of all certified frequency coordinators.

(v) The written consent from the li-censees specified in paragraphs (b)(2)(i) and (b)(2)(ii) or (b)(2)(iii)(A), (b)(2)(iii)(B) and (b)(2)(iii)C of this sec-tion shall specifically state all terms agreed to by the parties and shall be signed by the parties. The written con-sent shall be maintained by the oper-ator of the trunked station and be made available to the Commission upon request. The submission of a co-ordinated trunked application to the Commission shall include a certifi-cation from the applicant that written consent has been obtained from all li-censees specified in paragraphs (b)(2)(i) and (b)(2)(ii) or (b)(2)(iii)(A), (b)(2)(iii)(B) and (b)(2)(iii)(C) of this section that the written consent docu-ments encompass the complete under-standings and agreements of the par-ties as to such consent; and that the terms and conditions thereof are con-sistent with the Commission’s rules. Should a potential applicant disagree with a certified frequency coordina-tor’s determination that objectionable interference exists with respect to a given channel or channels, that poten-tial applicant may request the Com-mission to overturn the certified fre-quency coordinator’s determination. In

that event, the burden of proving by clear and convincing evidence that the certified frequency coordinator’s deter-mination is incorrect shall rest with the potential applicant. If a licensee has consented to the use of trunking, but later decides against the use of trunking, that licensee may request that the licensee(s) of the trunked sys-tem(s) cease the use of trunking. Should the trunked station(s) decline the licensee’s request, the licensee may request a replacement channel from the Commission. A new applicant whose interference contour overlaps the service contour of a trunked li-censee will be assigned the same chan-nel as the trunked licensee only if the trunked licensee consents in writing and a copy of the written consent is submitted to the certified frequency coordinator responsible for coordina-tion of the application.

(c) Trunking of systems licensed on paging-only channels or licensed in the Radiolocation Service (subpart F) is not permitted.

(d) Potential applicants proposing trunked operation may file written no-tice with any certified frequency coor-dinator for the pool (Public Safety or Industrial/Business) in which the appli-cant proposes to operate. The notice shall specify the channels on which the potential trunked applicant proposes to operate and the proposed effective radiated power, antenna pattern, height above ground, height above av-erage terrain and proposed channel bandwidth. On receipt of such a notice, the certified frequency coordinator shall notify all other certified fre-quency coordinators in the relevant pool within one business day. For a pe-riod of sixty days thereafter, no appli-cation will be accepted for coordina-tion which specifies parameters that would result in objectionable inter-ference to the channels specified in the notice. Potential applicants shall not file another notice for the same chan-nels within 10 km (6.2 miles) of the same location unless six months shall have elapsed since the filing of the last such notice. Certified frequency coordi-nators shall return without action, any coordination request which violates the terms of this paragraph (d).

(e) No more than 10 channels for trunked operation in the Industrial/ Business Pool may be applied for in a single application. Subsequent applica-tions, limited to an additional 10 chan-nels or fewer, must be accompanied by a certification, submitted to the cer-tified frequency coordinator coordi-nating the application, that all of the applicant’s existing channels author-ized for trunked operation have been constructed and placed in operation. Certified frequency coordinators are authorized to require documentation in support of the applicant’s certification that existing channels have been con-structed and placed in operation. Ap-plicants in the Public Safety Pool may request more than 10 channels at a sin-gle location provided that any applica-tion for more than 10 Public Safety Pool channels must be accompanied by a showing of sufficient need. The re-quirement for such a showing may be satisfied by submission of loading stud-ies demonstrating that requested chan-nels in excess of 10 will be loaded with 50 mobiles per channel within a five year period commencing with grant of the application.

(f) If a licensee authorized for trunked operation discontinues trunked operation for a period of 30 consecutive days, the licensee, within 7 days of the expiration of said 30 day pe-riod, shall file a conforming applica-tion for modification of license with the Commission. Upon grant of that application, new applicants may file for the same channel or channels not-withstanding the interference contour of the new applicant’s proposed chan-nel or channels overlaps the service contour of the station that was pre-viously engaged in trunked operation.

(o) Instrumentation. The reference level for showing compliance with the emission mask shall be established, ex-cept as indicated in §§ 90.210 (d), (e), and (k), using standard engineering prac-tices for the modulation characteristic used by the equipment under test. When measuring emissions in the 150– 174 MHz and 421–512 MHz bands the fol-lowing procedures will apply. A suffi-cient number of sweeps must be meas-ured to insure that the emission profile is developed. If video filtering is used, its bandwidth must not be less than the instrument resolution bandwidth. For frequencies more than 50 kHz removed from the edge of the authorized band-width a resolution of at least 100 kHz must be used for frequencies below 1000 MHz. Above 1000 MHz the resolution bandwidth of the instrumentation must be at least 1 MHz. If it can be shown that use of the above instrumen-tation settings do not accurately rep-

resent the true interference potential of the equipment under test, then an alternate procedure may be used pro-vided prior Commission approval is ob-tained.

§ 90.215 Transmitter measurements. (a) The licensee of each station shall

employ a suitable procedure to deter-mine that the carrier frequency of each transmitter authorized to operate with an output power in excess of two watts is maintained within the tolerence pre-scribed in § 90.213. This determination shall be made, and the results entered in the station records in accordance with the following:

(1) When the transmitter is initially installed;

(2) When any change is made in the transmitter which may affect the car-rier frequency or its stability.

(b) The licensee of each station shall employ a suitable procedure to deter-mine that each transmitter authorized to operate with an output power in ex-cess of two watts does not exceed the maximum figure specified on the cur-rent station authorization. On author-izations stating only the input power to the final radiofrequency stage, the maximum permissible output power is 75 percent for frequencies below 25 MHz and 60 percent of the input power for frequencies above 25 MHz. If a non-DC final radiofrequency stage is utilized, then the output power shall not exceed 75 percent of the input power. This de-termination shall be made, and the re-sults thereof entered into the station records, in accordance with the fol-lowing:


(2) When any change is made in the transmitter which may increase the transmitter power input.

(c) The licensee of each station shall employ a suitable procedure to deter-mine that the modulation of each transmitter, which is authorized to op-erate with an output power in excess of two watts, does not exceed the limits specified in this part. This determina-tion shall be made and the following results entered in the station records, in accordance with the following:


(2) When any change is made in the transmitter which may affect the mod-ulation characteristics.

(d) The determinations required by paragraphs (a), (b), and (c) of this sec-tion may, at the opinion of the li-censee, be made by a qualified engi-neering measurement service, in which case the required record entries shall show the name and address of the engi-neering measurement service as well as the name of the person making the measurements.

(e) In the case of mobile transmit-ters, the determinations required by paragraphs (a) and (c) of this section may be made at a test or service bench: Provided, That the measurements are made under load conditions equivalent to actual operating conditions; and provided further, that after installa-tion in the mobile unit the transmitter is given a routine check to determine that it is capable of being received satisfactorly by an appropriate re-ceiver.

§ 90.217 Exemption from technical standards.

Except as noted herein, transmitters used at stations licensed below 800 MHz on any frequency listed in subparts B and C of this part or licensed on a busi-ness category channel above 800 MHz which have an output power not ex-ceeding 120 milliwatts are exempt from the technical requirements set out in this subpart, but must instead comply with the following:

(a) For equipment designed to oper-ate with a 25 kHz channel bandwidth, the sum of the bandwidth occupied by the emitted signal plus the bandwidth required for frequency stability shall be adjusted so that any emission ap-pearing on a frequency 40 kHz or more removed from the assigned frequency is attenuated at least 30 dB below the unmodulated carrier.

(b) For equipment designed to oper-ate with a 12.5 kHz channel bandwidth, the sum of the bandwidth occupied by the emitted signal plus the bandwidth required for frequency stability shall be adjusted so that any emission ap-pearing on a frequency 25 kHz or more removed from the assigned frequency is attenuated at least 30 dB below the unmodulated carrier.

§ 90.219 Use of signal boosters. Licensees authorized to operate radio

systems in the frequency bands above 150 MHz may employ signal boosters at fixed locations in accordance with the following criteria:

(a) The amplified signal is retrans-mitted only on the exact frequency(ies) of the originating base, fixed, mobile, or portable station(s). The booster will fill in only weak signal areas and can-not extend the system’s normal signal coverage area.

(b) Class A narrowband signal boost-ers must be equipped with automatic gain control circuitry which will limit the total effective radiated power (ERP) of the unit to a maximum of 5 watts under all conditions. Class B broadband signal boosters are limited to 5 watts ERP for each authorized fre-quency that the booster is designed to amplify.

(c) Class A narrowband boosters must meet the out-of-band emission limits of § 90.210 for each narrowband channel that the booster is designed to amplify. Class B broadband signal boosters must meet the emission limits of § 90.210 for frequencies outside of the booster’s de-signed passband.

(d) Class B broadband signal boosters are permitted to be used only in con-fined or indoor areas such as buildings, tunnels, underground areas, etc., or in remote areas, i.e., areas where there is little or no risk of interference to other users.

(e) The licensee is given authority to operate signal boosters without sepa-rate authorization from the Commis-sion. Certificated equipment must be employed and the licensee must ensure that all applicable rule requirements are met.

(f) Licensees employing either Class A narrowband or Class B broadband signal boosters as defined in § 90.7 are responsible for correcting any harmful interference that the equipment may cause to other systems. Normal co- channel transmissions will not be con-sidered as harmful interference. Li-censees will be required to resolve in-terference problems pursuant to § 90.173(b).

In the Industrial/Business Pool, on frequencies designated with an ‘‘LR’’ in the coordinator column of the frequency table in § 90.35(b)(3), such a control station may be assigned any mobile service station frequency avail-able for assignment to mobile stations. Such operation is on a secondary basis to use of the frequency for regular mo-bile service communications.

(3) Control and fixed stations in the Public Safety Pool may be authorized on a temporary basis to operate on fre-quencies available for base and mobile stations between 152 and 450 MHz, where there is an adequate showing that such operations cannot be con-ducted on frequencies allocated for as-signment to operational fixed stations. Such operation will not be authorized initially or renewed for periods in ex-cess of one year. Any such authoriza-tion shall be subject to immediate ter-mination if harmful interference is caused to stations in the mobile serv-ice, or if the particular frequency is re-quired for mobile service operations in the area concerned.

(b) [Reserved] (c) A base station which is used inter-

mittently as a control station for one or more associated mobile relay sta-tions of the same licensee shall operate only on the mobile service frequency assigned to the associated mobile relay station when operating as a base sta-tion and on the mobile service fre-quency assigned to the associated mo-bile station when operating as a con-trol station. Authority for such dual classification and use must be shown on the station authorization. When op-erating as a control station, the li-censee must meet all control station requirements. In the Industrial/Busi-ness Pool, on frequencies designated with an ‘‘LR’’ in the coordinator col-umn of the frequency table in § 90.35(b)(3), base stations used inter-mittently as control stations shall op-erate only on a mobile service fre-quency which is available for assign-ment to base stations.

(2) All authorizations are subject to the condition that no harmful inter-ference will be caused to television re-ception on Channels 4 and 5.

(3) The applicant must agree to eliminate any harmful interference caused by his operation to TV recep-tion on either Channel 4 or 5 that might develop by whatever means are necessary. Such action must be taken within 90 days of notification by the Commission. If such interference is not eliminated within the 90-day period, operation of the fixed station will be discontinued.

(4) Vertical polarization must be used.

(5) Whenever it is proposed to locate a 72–76 MHz fixed station less than 128 km (80 mi.) but more than 16 km (10 mi.) from the site of a TV transmitter operating on either channel 4 or 5, or from the post office of a community in which such channels are assigned but not in operation, the fixed station shall be authorized only if there are fewer than 100 family dwelling units (as de-fined by the U.S. Bureau of the Cen-sus), excluding units 112 or more km (70 mi.) distant from the TV antenna site, located within a circle centered at the location of the proposed fixed station.

The radius shall be determined by use of the following chart entitled, ‘‘Chart for Determining Radius From Fixed Station in 72–76 MHz Band to Inter-ference Contour Along Which 10 Per-cent of Service From Adjacent Channel Television Station Would Be De-stroyed.’’ Two charts are available, one for Channel 4, and one for Channel 5. The Commission may, however, in a particular case, authorize the location of a fixed station within a circle con-taining 100 or more family dwelling units upon a showing that:

(i) The proposed site is the only suit-able location.

(ii) It is not feasible, technically or otherwise, to use other available fre-quencies.

(iii) The applicant has a plan to con-trol any interference that might de-velop to TV reception from his oper-ations.

(iv) The applicant is financially able and agrees to make such adjustments in the TV receivers affected as may be necessary to eliminate any inter-ference caused by his operations.

(v) All applications seeking authority to operate with a separation of less than 16 km (10 mi.) will be returned without action.

(b) The following criteria governs the authorization and use of frequencies in the 72–76 MHz band by mobile stations in the Industrial/Business Pool.

(1) Mobile operation on frequencies in the 72–76 MHz band is subject to the condition that no interference is caused to the reception of television stations operating on Channel 4 or 5. Interference will be considered to occur whenever reception of a regularly used television signal is impaired by signals radiated by stations operating under these rules in the 72 to 76 MHz band re-gardless of the quality of such recep-tion or the strength of the signal used. In order to minimize the hazard of such interference, it shall be the duty of the licensee to determine whether inter-ference is being caused to television re-ception, wherever television receivers other than those under the control of the licensee, are located within 31 m. (100 ft.) of any point where the stations licensed under these rules may be oper-ated. In any case, it shall be the re-sponsibility of the licensee to correct,

at its own expense, any such inter-ference and if the interference cannot be eliminated by the application of suitable techniques, the operation of the offending transmitter shall be sus-pended. If the complainant refuses to permit the licensee to apply remedial techniques which demonstrably will eliminate the interference without im-pairment of the original reception, the licensee is absolved of further responsi-bility.

(2) The maximum transmitter output power that will be authorized is 1 watt; and each station authorized will be classified and licensed as a mobile sta-tion. Any units of such a station, how-ever, may be used to provide the oper-ational functions of a base or fixed sta-tion. The antennas of transmitters op-erating on these frequencies must be

directly mounted or installed upon the transmitting unit: Except that when permanently installed aboard a vehi-cle, antenna and transmitter may be separated as required for convenience in mounting. Horizontal polarization will not be allowed; and the gain of an-tennas employed shall not exceed that of a halfwave dipole. The maximum bandwidth that will be authorized is 20 kHz. Tone control transmissions are permitted.

(c) Radio remote control of models is permitted on frequencies 10 kHz re-moved from these frequencies author-ized for fixed and mobile operations in the 72–76 MHz band. Remote control op-erations are secondary to operation of fixed and mobile stations as provided for in this section.

§ 90.263 Substitution of frequencies below 25 MHz.

Frequencies below 25 MHz when shown in the radio pool frequency list-ings under this part will be assigned to base or mobile stations only upon a satisfactory showing that, from a safe-ty of life standpoint, frequencies above 25 MHz will not meet the operational requirements of the applicant. These frequencies are available for assign-ment in many areas; however, in indi-vidual cases such assignment may be impracticable due to conflicting fre-quency use authorized to stations in other services by this and other coun-tries. In such cases, a substitute fre-quency, if found available, may be as-signed from the following bands: 1705– 1750 kHz, 2107–2170 kHz, 2194–2495 kHz, 2506–2850 kHz, 3155–3400 kHz, or 4438– 4650 kHz. Since such assignments are in certain instances subject to additional technical and operation limitations, it is necessary that each application also include precise information concerning transmitter output power, type and di-rectional characteristics, if any, of the antenna, and the minimum necessary hours of operation. (This section is not applicable to the Radiolocation Serv-ice, subpart F of this part.)

§ 90.305 Location of stations. (a) The transmitter site(s) for base

station(s), including mobile relay sta-tions, shall be located not more than 80 km. (50 mi.) from the geographic center of the urbanized area listed in § 90.303.

(b) Mobile units shall be operated within 48 km. (30 mi.) of their associ-ated base station or stations. Such units may not be operated aboard air-craft in flight except as provided for in § 90.315(i).

(c) Control stations must be located within the area of operation of the mo-bile units.

(d) Base and control stations shall be located a minimum of 1.6 km. (1 mi.) from local television stations oper-ating on UHF TV channels separated by 2, 3, 4, 5, 7, and 8 TV channels from the television channel in which the base station will operate.

§ 90.307 Protection criteria. The tables and figures listed in

§ 90.309 shall be used to determine the effective radiated power (ERP) and an-tenna height of the proposed land mo-bile base station and the ERP for the associated control station (control sta-tion antenna height shall not exceed 31 meters (100 feet) above average terrain (AAT)).

(a) Base stations operating on the frequencies available for land mobile use in any urbanized area and having an antenna height (AAT) less than 152 meters (500 feet) shall afford protection

to co-channel and adjacent channel tel-evision stations in accordance with the values set out in tables A and E of § 90.309, except for channel 15 in New York, NY, and Cleveland, OH, and channel 16 in Detroit, MI, where pro-tection will be in accordance with the values set forth in tables B and E in 47 CFR 90.309.

(b) For base stations having antenna heights between 152 and 914 meters (500–3000 feet) above average terrain, the effective radiated power must be reduced below 1 kilowatt in accordance with the values shown in the power re-duction graph in Figure A in § 90.309, except for channel 15 in New York, NY, and Cleveland, OH, and channel 16 in Detroit, MI, where the effective radi-ated power must be reduced in accord-ance with Figure B in § 90.309. For heights of more than 152 meters (500 feet) above average terrain, the dis-tance to the radio path horizon will be calculated assuming smooth earth. If the distance so determined equals or exceeds the distance to the Grade B contour of a co-channel TV station (Grade B contour defined in § 73.683(a) of this chapter), an authorization will not be granted unless it can be shown that actual terrain considerations are such as to provide the desired protec-tion at the Grade B contour, or that the effective radiated power will be fur-ther reduced so that, assuming free space attenuation, the desired protec-tion at the Grade B contour will be achieved.

(c) Mobile units and control stations operating on the frequencies available for land mobile use in any given urban-ized area shall afford protection to co- channel and adjacent channel tele-vision stations in accordance with the values set forth in table C in § 90.309 and paragraph (d) of this section except for channel 15 in New York, NY, and Cleveland, OH, and channel 16 in De-troit, MI, where protection will be in accordance with the values set forth in table D in § 90.309 and paragraph (d) of this section.

(d) The minimum distance between a land mobile base station which has as-sociated mobile units and a protected adjacent channel television station is 145 km (90 miles).

47 CFR Ch. I (10–1–10 Edition) § 90.309

(e) The television stations to be pro-tected (co-channel, adjacent channel, IM, and IF) in any given urbanized area, in accordance with the provisions of paragraphs (a), (b), (c), and (d) of this section, are identified in the Com-mission’s publication ‘‘TV stations to be considered in the preparation of Ap-plications for Land Mobile Facilities in the Band 470–512 MHz.’’ The publication is available at the offices of the Fed-eral Communications Commission in Washington, DC or upon the request of interested persons.

[72 FR 35197, June 27, 2007]

§ 90.309 Tables and figures. (a) Directions for using the tables. (1)

Using the method specified in § 1.958 of this chapter, determine the distances between the proposed land mobile base station and the protected co-channel television station and between the pro-posed land mobile base station and the protected adjacent channel television station. If the exact mileage does not appear in table A for protected co- channel television stations (or table B for channel 15 in New York and Cleve-land and channel 16 in Detroit) or table E for protected adjacent channel tele-vision stations, the next lower mileage separation figure is to be used.

(2) Entering the proper table at the mileage figure found in paragraph (a)(1) of this section, find opposite, a selection of powers that may be used for antenna heights ranging from 15 m (50 ft) to 152.5 m (500 ft) (AAT). If the exact antenna height proposed for the land mobile base station does not ap-pear in the proper table, use the power figure beneath the next greater an-tenna height.

(3) The lowest power found using the tables mentioned in paragraphs (a)(1) and (a)(2) of this section is the max-imum power that may be employed by the proposed land mobile base station.

(4) In determining the average ele-vation of the terrain, the elevations be-tween 3.2 kilometers (2 miles) and 16 kilometers (10 miles) from the antenna site are employed. Profile graphs shall

be drawn for a minimum of eight radials beginning at the antenna site and extending 16 kilometers (10 miles). The radials should be drawn starting with true north. At least one radial should be constructed in the direction of the nearest co-channel and adjacent channel UHF television stations. The profile graph for each radial shall be plotted by contour intervals of from 12.2 meters (40 feet) to 30.5 meters (100 feet) and, where the data permits, at least 50 points of elevation (generally uniformly spaced) should be used for each radial. For very rugged terrain, 61 meters (200 feet) to 122 meters (400 foot) contour intervals may be used. Where the terrain is uniform or gently slop-ing, the smallest contour interval indi-cated on the topographic chart may be used. The average elevation of the 12.8 kilometer (8 mile) distance between 3.2 kilometers (2 miles) and 16 kilometers (10 miles) from the antenna site should be determined from the profile graph for each radial. This may be obtained by averaging a large number of equally spaced points, by using a planimeter, or by obtaining the median elevation (that exceeded by 50 percent of the dis-tance) in sectors and averaging those values. In the preparation of the profile graphs, the elevation or contour inter-vals may be taken from U.S. Geological Survey Topographic Maps, U.S. Army Corps of Engineers Maps, or Tennessee Valley Authority Maps. Maps with a scale of 1:250,000 or larger (such as 1:24,000) shall be used. Digital Terrain Data Tapes, provided by the National Cartographic Institute, U.S. Geologic Survey, may be utilized in lieu of maps, but the number of data points must be equal to or exceed that speci-fied above. If such maps are not pub-lished for the area in question, the next best topographic information should be used.

(5) Applicants for base stations in the Miami, FL, urbanized area may, in lieu of calculating the height of average terrain, use 3 m (10 ft) as the average terrain height.

§ 90.313 Frequency loading criteria. (a) Except as provided for in para-

graph (b) of this section, the maximum channel loading on frequencies in the 470–512 MHz band is as follows:

(1) 50 units for systems eligible in the Public Safety Pool (see § 90.20(a)).

(2) 90 units for systems eligible in the Industrial/Business Pool (see § 90.35(a)).

(b) If a licensee has exclusive use of a frequency, then the loading standards in paragraph (a) of this section, may be exceeded. If it is a shared channel, the loading standards can be exceeded upon submission of a signed statement by all those sharing the channel agreeing to the increase.

(c) A unit is defined as a mobile transmitter-receiver. Loading stand-ards will be applied in terms of the number of units actually in use or to be placed in use within 8 months fol-lowing authorization. A licensee will be required to show that an assigned fre-quency pair is at full capacity before it may be assigned a second or additional frequency pair. Channel capacity may be reached either by the requirements of a single licensee or by several users sharing a channel. Until a channel is loaded to capacity it will be available for assignment to other users in the same area. A frequency pair may be re-assigned at distances 64 km. (40 mi.), 32 km. (20 mi.) for Channel 15, Chicago; Channel 20, Philadelphia; and Channel 17, Washington, or more from the loca-tion of base stations authorized on that pair without reference to loading at the point of original installation. Fol-lowing authorization, the licensee shall notify the Commission either during or at the close of the 8 month period of the number of units in operation. In the Industrial Radio Services, if the base station facility is to be used by more than a single licensee, the fre-quency assigned to it will not be reas-signed for use by another facility with-in 64 km. (40 mi.) or 32 km. (20 mi.) where applicable for a period of 12 months, Provided, That the facility is

constructed within 90 days from the date of the first grant, meets the load-ing standards to at least 50 percent within 9 months, and meets all loading standards within 12 months.

NOTE: To determine the maximum permis-sible effective radiated power:

(1) As specified in § 73.611 determine the distance between the proposed station and the cochannel television station. If the exact distance does not appear in table 1 of this section, the next lower distance separation is to be used.

(2) Opposite this distance figure ERPs are given that may be used for antenna heights of 30.5, 45 or 61 meters (100, 150 or 200 ft) ASL. If the exact antenna height is not shown, the ERP allowed will be that shown for the next higher antenna height.

(e) Shore stations communicating point-to-point with offshore stations will be permitted at least the same ERP as the offshore station, but only in the direction of the offshore station. A directional antenna shall be used and the rearward radiated power from the antenna in a sector ±221⁄2° from the line joining the shore antenna to the co-channel television station shall not ex-ceed those shown in table 2 of this sec-tion.

NOTE: As an example of the use of tables 1 and 2, assume an offshore station located 290 km (180 mi) from TV Channel 17 located in Bude, Miss. with an antenna height of 30.5 m (100 ft). Table 1 allows this station to operate with 250 W ERP. Now assume the shore sta-tion communicating with the offshore sta-tion is 48 km (30 mi) from the offshore sta-tion and 241 km (150 mi) from Bude, Miss. The shore station antenna height is 152.5 m (500 ft) above ground. The shore station will be allowed the same ERP as the offshore sta-tion (250 W) in the direction of the offshore station. Table 2 indicates that the effective radiated power in a sector <±> 221⁄2° from the line joining the shore antenna to Bude, Miss. can only be 15 W. Consequently, a directional antenna must be used whose minimum front- to-back ratio over this 45° sector must be at least 12.2 dB. (250 W forward power to 15 W rearward power is a power ratio of 16.6 or 12.2 dB).

(f) To provide cochannel protection to television stations, no shore station will be allowed closer than 193 km miles) from the cochannel television station.

(g) To provide adjacent channel pro-tection to television stations, no shore or offshore station shall be allowed within 128 kilometers (80 miles) of the adjacent channel television station.

(h) Mobile stations shall not operate closer to shore than 6.4 km (4 miles) be-yond the three mile limit and shall not operate with an ERP in excess of 100

services in the Intelligent Transpor-tation Systems radio service are set forth in this subpart.

[64 FR 66410, Nov. 26, 1999]

§ 90.351 Location and Monitoring Serv-ice.

These provisions authorize the li-censing of systems in the Location and Monitoring Service (LMS). LMS sys-tems utilize non-voice radio techniques to determine the location and status of mobile radio units. LMS licensees au-thorized to operate a system in the 902– 928 MHz band may serve individuals, federal government agencies, and enti-ties eligible for licensing in this part 90.

(a) Each application to license an LMS system shall include the fol-lowing supplemental information:

(1) A detailed description of the man-ner in which the system will operate, including a map or diagram.

(2) The necessary or occupied band-width of emission, whichever is great-er.

(3) The data transmission character-istics as follows:

(i) The vehicle location update rates; (ii) Specific transmitter modulation

techniques used; (iii) For codes and timing scheme: A

table of bit sequences and their alpha-numeric or indicator equivalents, and a statement of bit rise time, bit trans-mission rates, bit duration, and inter-val between bits;

(iv) A statement of amplitude-versus- time of the interrogation and reply for-mats, and an example of a typical mes-sage transmission and any synchro-nizing pulses utilized.

(4) A plan to show the implementa-tion schedule during the initial license term.

(b) LMS stations are exempted from the identification requirements of § 90.425; however, the Commission may impose automatic station identifica-tion requirements when determined to be necessary for monitoring and en-forcement purposes.

§ 90.353 LMS operations in the 902–928 MHz band.

LMS systems may be authorized within the 902–928 MHz band, subject to the conditions in this section. LMS li-

censees are required to maintain what-ever records are necessary to dem-onstrate compliance with these provi-sions and must make these records available to the Commission upon re-quest:

(a) LMS operations will not cause in-terference to and must tolerate inter-ference from industrial, scientific, and medical (ISM) devices and radio-location Government stations that op-erate in the 902–928 MHz band.

(b) LMS systems are authorized to transmit status and instructional mes-sages, either voice or non-voice, so long as they are related to the location or monitoring functions of the system.

(c) LMS systems may utilize store and forward interconnection, where ei-ther transmissions from a vehicle or object being monitored are stored by the LMS provider for later trans-mission over the public switched net-work (PSN), or transmissions received by the LMS provider from the PSN are stored for later transmission to the ve-hicle or object being monitored. Real- time interconnection between vehicles or objects being monitored and the PSN will only be permitted to enable emergency communications related to a vehicle or a passenger in a vehicle. Such real-time, interconnected com-munications may only be sent to or re-ceived from a system dispatch point or entities eligible in the Public Safety or Special Emergency Radio Services. See subparts B and C of this part.

(d) Multilateration LMS systems will be authorized on a primary basis with-in the bands 904–909.75 MHz and 921.75– 927.25 MHz. Additionally, multilateration and non- multilateration systems will share the 919.75–921.75 MHz band on a co-equal basis. Licensing will be on the basis of Economic Areas (EAs) for multilateration systems, with one ex-clusive EA license being issued for each of these three sub-bands. Except as pro-vided in paragraph (f) of this section, multilateration EA licensees may be authorized to operate on only one of the three multilateration bands within a given EA. Additionally, EA multilateration LMS licenses will be conditioned upon the licensee’s ability to demonstrate through actual field tests that their systems do not cause

unacceptable levels of interference to 47 CFR part 15 devices.

(e) Multilateration EA-licensed sys-tems and grandfathered automatic ve-hicle monitoring service (AVM) sys-tems (see § 90.363) are authorized on a shared basis and must cooperate in the selection and use of frequencies in ac-cordance with § 90.173(b).

(f) Multilateration EA licensees may be authorized to operate on both the 919.75–921.75 MHz and 921.75–927.75 MHz bands within a given EA (see § 90.209(b)(5)).

(g) Multilateration LMS systems whose primary operations involve the provision of vehicle location services, may provide non-vehicular location services.

(h) Non-multilateration stations are authorized to operate on a shared, non- exclusive basis in the 902–904 MHz and 909.75–921.75 MHz sub-bands. Non- multilateration systems and multilateration systems will share the 919.75–921.75 MHz band on a co-equal basis. Non-multilateration LMS sys-tems may not provide non-vehicular lo-cation services. The maximum antenna height above ground for non- multilateration LMS systems is 15 me-ters.

(i) Non-multilateration LMS licenses will be issued on a site-by-site basis, except that municipalities or other governmental operatives may file jointly for a non-multilateration li-cense covering a given U.S. Depart-ment of Commerce Bureau of Economic Analysis Economic Area (EA). Such an application must identify all planned sites. After receiving the license, the non-multilateration EA licensee must notify the Commission if sites are de-leted or if new sites are added, before those sites may be put into operation.

[60 FR 15253, Mar. 23, 1995, as amended at 62 FR 52044, Oct. 6, 1997; 72 FR 35198, June 27, 2007; 75 FR 19284, Apr. 14, 2010]

§ 90.355 LMS operations below 512 MHz.

Applications requiring not more than 25 kHz bandwidth per frequency in the 25–50 MHz, 150–170 MHz, and 450–512 MHz bands may use either base-mobile frequencies currently assigned the ap-plicant, or be assigned base-mobile fre-quencies available in the service in

which eligibility has been established, provided that:

(a) For transmission between vehi-cles and base stations, each frequency in a single-frequency mode of operation will provide location data for approxi-mately 200 vehicles, or both frequencies in a two-frequency mode of operation will provide location data for approxi-mately 400 vehicles, except that for fre-quencies in the 450–512 MHz band that are assigned in pairs in accordance with the allocation plan for the band, the requirement is that location data be provided for approximately 200 vehi-cles for each frequency pair; and a showing is made that 50 percent of the vehicles will be in operation within the system by the end of the second year of the initial license term, and 70 percent will be in operation within the system by the end of the initial license term; except that if these vehicle loading standards will not be met, frequencies will be assigned only on a secondary non-interference basis to any author-ized radiotelephony operation.

(b) The minimum separation between a proposed LMS station and the near-est co-channel base station of another licensee operating a voice system is 75 miles (120 km) for a single frequency mode of operation or 35 miles (56 km) for a two-frequency mode of operation. Where the minimum mileage separa-tion cannot be achieved, agreement to the use of F1D, F2D, G1D, G2D or P0N emission must be received from all ex-isting co-channel licensees using voice emissions within the applicable mile-age limits. If there is interference with voice operations and required agree-ment was not received, or operation was authorized on a secondary non-in-terference basis, the licensee of the LMS system is responsible for elimi-nating the interference.

(c) Frequencies additional to any as-signed under paragraph (a) of this sec-tion will not be assigned to the same li-censee at any stations located within 64 km (40 miles) of any station in which the licensee holds an interest until each of such licensee’s frequencies for LMS operation is shown to accommo-date not less than 90 percent of the fre-quency loading requirements specified in paragraph (a) of this section.

47 CFR Ch. I (10–1–10 Edition) § 90.373

§ 90.373 Eligibility in the DSRCS. The following entities are eligible to

hold an authorization to operate Road-side units in the DSRCS:

(a) Any territory, possession, state, city, county, town or similar govern-mental entity.

(b) Any entity meeting the eligibility requirements of §§ 90.33 or 90.35.

[69 FR 46443, Aug. 3, 2004]

§ 90.375 RSU license areas, commu-nication zones and registrations

(a) DSRCS Roadside Units (RSUs) in the 5850–5925 MHz band are licensed on the basis of non-exclusive geographic areas. Governmental applicants will be issued a geographic area license based on the geo-political area encompassing the legal jurisdiction of the entity. All other applicants will be issued a geo-graphic area license for their proposed area of operation based on county(s), state(s) or nationwide.

(b) Applicants who are approved in accordance with FCC Form 601 will be granted non-exclusive licenses for all non-reserved DSRCS frequencies (see § 90.377). Such licenses serve as a pre-requisite of registering individual RSUs located within the licensed geo-graphic area described in paragraph (a) of this section. Licensees must register each RSU in the Universal Licensing System (ULS) before operating such RSU. RSU registrations are subject, inter alia, to the requirements of § 1.923 of this chapter as applicable (antenna structure registration, environmental concerns, international coordination, and quiet zones). Additionally, RSUs at locations subject to NTIA coordination (see § 90.371(b) may not begin operation until NTIA -approval is received. Reg-istrations are not effective until the Commission posts them on the ULS.

(c) Licensees must operate each RSU in accordance with the Commission’s Rules and the registration data posted on the ULS for such RSU. Licensees

must register each RSU for the small-est communication zone needed (for the DSRC-based intelligent transpor-tation systems application) using one of the following four communication zones:

Copies of the ASTM E2213–03 DSRC Standard can be obtained from ASTM International, 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA 19428–2959. Copies may also be obtained from ASTM via the Internet at http://www.astm.org. The ASTM-DSRC Standard limits output power to 28.8 dBm but allows more power to overcome cable losses to the an-tenna as long as the antenna input power does not exceed 28.8 dBm and the EIRP does not exceed 44.8 dBm. However, specific channels and categories of uses have additional limi-tations under the ASTM-DSRC Standard.

§ 90.377 Frequencies available; max-imum EIRP and antenna height, and priority communications.

(a) Licensees shall transmit only the power (EIRP) needed to communicate with an On-Board Unit (OBU) within the communications zone and must take steps to limit the Roadside Unit (RSU) signal within the zone to the maximum extent practicable.

(b) Frequencies available for assign-ment to eligible applicants within the 5850–5925 MHz band for RSUs and the maximum EIRP permitted for an RSU with an antenna height not exceeding 8 meters above the roadway bed surface are specified in the table below.

The EIRP is measured as the maximum EIRP toward the horizon or horizontal, whichever is greater, of the gain associated with the main or center of the transmission beam. The RSU antenna height shall not exceed 15 meters above the roadway bed surface.

2 Channel 172 is designated for public safety applications involving safety of life and property. 3 Channel Nos. 174/176 may be combined to create a twenty megahertz channel, designated Channel No. 175. Channels 180/

182 may be combined to create a twenty-megahertz channel, designated Channel No. 181. 4 Channel 184 is designated for public safety applications involving safety of life and property. Only those entities meeting the

requirements of § 90.373(a) are eligible to hold an authorization to operate on this channel.

(c) Except as provided in paragraphs (d) and (e) of this section, non-reserve DSRCS channels are available on a shared basis only for use in accordance with the Commission’s rules. All li-censees shall cooperate in the selection and use of channels in order to reduce interference. This includes monitoring for communications in progress and any other measures as may be nec-essary to minimize interference. Li-censees of RSUs suffering or causing harmful interference within a commu-nications zone are expected to cooper-ate and resolve this problem by mutu-ally satisfactory arrangements. If the licensees are unable to do so, the Com-mission may impose restrictions in-cluding specifying the transmitter power, antenna height and direction, additional filtering, or area or hours of operation of the stations concerned. Further the use of any channel at a given geographical location may be de-nied when, in the judgment of the Com-mission, its use at that location is not in the public interest; use of any such channel may be restricted as to speci-fied geographical areas, maximum power, or such other operating condi-tions, contained in this part or in the station authorization.

(d) Safety/public safety priority. The following access priority governs all DSRCS operations:

(1) Communications involving the safety of life have access priority over all other DSRCS communications;

(2) Subject to a control channel pri-ority system management strategy (see ASTM E2213–03 DSRC Standard at § 4.1.1.2(4)), DSRCS communications in-volving public safety have access pri-ority over all other DSRC communica-tions not listed in paragraph (d)(1) of

this section. Roadside Units (RSUs) op-erated by state or local governmental entities are presumptively engaged in public safety priority communications.

(e) Non-priority communications. DSRCS communications not listed in paragraph (d) of this section, are non- priority communications. If a dispute arises concerning non-priority commu-nications, the licensee of the later-reg-istered RSU must accommodate the op-eration of the early registered RSU, i.e., interference protection rights are date-sensitive, based on the date that the RSU is first registered (see § 90.375) and the later-registered RSU must modify its operations to resolve the dispute in accordance with paragraph (f) of this section.

(f) Except as otherwise provided in the ASTM–DSRC Standard (see § 90.379) for the purposes of paragraph (e) of this section, objectionable interference will be considered to exist when the Com-mission receives a complaint and the difference in signal strength between the earlier-registered RSU and the later-registered RSU (anywhere within the earlier-registered RSU’s commu-nication zone) is 18 dB or less (co-chan-nel). Later-registered RSUs causing ob-jectionable interference must correct the interference immediately unless written consent is obtained from the li-censee of the earlier-registered RSU.

measures as may be necessary to mini-mize the potential for causing inter-ference.

(f) Stations licensed in this part shall not continuously radiate an unmodulated carrier except where re-quired for tests as permitted in § 90.405, except where specifically permitted by this part, where specifically authorized in the station authorization, or on an as needed basis in the Radiolocation Radio Service.

(g) The radiations of the transmitter shall be suspended immediately upon detection or notification of a deviation from the technical requirements of the station authorization and until such deviation is corrected. For trans-missions concerning the imminent safety-of-life or property, the trans-missions shall be suspended as soon as the emergency is terminated.

[43 FR 54791, Nov. 22, 1978; 44 FR 32220, June 5, 1979, as amended at 59 FR 59965, Nov. 21, 1994]

§ 90.405 Permissible communications.

(a) Stations licensed under this part may transmit only the following types of communication:

(1) Any communication related di-rectly to the imminent safety-of-life or property;

(2) Communications directly related and necessary to those activities which make the licensee eligible for the sta-tion license held under this part. In ad-dition, when communication service is provided under the cooperative sharing provisions of § 90.179, the licensee pro-viding such service may transmit com-munications related to the activities for which the parties receiving the service would be eligible to be licensed.

(3) Communications for testing pur-poses required for proper station and system maintenance. However, each li-censee shall keep such tests to a min-imum and shall employ every measure to avoid harmful interference.

(b) The provisions contained in para-graph (a) of this section do not apply where a single base station licensee has been authorized to use a channel above 470 MHz on an exclusive basis, or to stations licensed under this part that

are classified as CMRS providers under part 20 of this chapter.

station without restriction as to type, service, or licensee when the commu-nications involved relate directly to the imminent safety-of-life or prop-erty.

(b) Any station licensed under this part may communicate with any other station licensed under this part, with U.S. Government stations, and with foreign stations, in connection with mutual activities, provided that where the communication involves foreign stations prior approval of the Commis-sion must be obtained, and such com-munication must be permitted by the government that authorizes the foreign station. Communications by Public Safety Pool eligibles with foreign sta-tions will be approved only to be con-ducted in accordance with Article 5 of the Inter-American Radio Agreement, Washington, DC, 1949, the provisions of which are set forth in § 90.20(b).


§ 90.419 Points of communication.

Normally, operations licensed under this part are intended to provide intrastation mobile communications. For example, a base station is intended to communicate with its associated mobile stations and mobile stations are intended to communicate between as-sociated mobile stations and associated base stations of the licensee. Accord-ingly, operations between base stations at fixed locations are permitted only in the following situations:

(a) Base stations licensed under sub-part T of this part and those in the Public Safety Pool that operate on fre-quencies below 450 MHz, may commu-nicate on a secondary basis with other base stations, operational fixed sta-tions, or fixed receivers authorized in these services or pools.

(b) Base stations licensed on any fre-quency in the Industrial/Business Pool and on base stations frequencies above 450 MHz in the Public Safety Pool may communicate on a secondary basis with other base stations, operational fixed stations, or fixed receivers au-thorized in these pools only when:

(1) The messages to be transmitted are of immediate importance to mobile stations; or

(2) Wireline communications facili-ties between such points are inoper-ative, economically impracticable, or unavailable from communications common carrier sources. Temporary unavailability due to a busy wireline circuit is not considered to be within the provisions of this paragraph.

(c) Operational fixed stations may communicate with units of associated mobile stations only on a secondary basis.

(d) Operational fixed stations li-censed in the Industrial/Business Pool may communicate on a secondary basis with associated base stations licensed in these services when:

(1) The messages to be transmitted are of immediate importance to mobile stations; or

(2) Wireline communications facili-ties between such points are inoper-ative, economically impracticable, or unavailable from communications common carrier sources. Temporary unavailability due to a busy wireline circuit is not considered to be within the provisions of this paragraph.

(e) Travelers’ Information Stations are authorized to transmit certain in-formation to members of the traveling public (see § 90.242).

(f) CMRS licensees in the SMR cat-egories of part 90, subpart S, CMRS providers authorized in the 220 MHz service of part 90, subpart T, CMRS paging operations as defined by part 90, subpart P and for-profit interconnected business radio services with eligibility defined by § 90.35 are permitted to uti-lize their assigned spectrum for fixed services on a co-primary basis with their mobile operations.

[61 FR 45356, Aug. 29, 1996, as amended at 62 FR 18933, Apr. 17, 1997; 72 FR 35199, June 27, 2007]

§ 90.421 Operation of mobile station units not under the control of the licensee.

Mobile stations, as defined in § 90.7, include vehicular-mounted and hand- held units. Such units may be operated by persons other than the licensee, as provided for below, when necessary for the licensee to meet its requirements in connection with the activities for which it is licensed. If the number of

such units, together with units oper-ated by the licensee, exceeds the num-ber of mobile units authorized to the li-censee, license modification is re-quired. The licensee is responsible for taking necessary precautions to pre-vent unauthorized operation of such units not under its control.

(a) Public Safety Pool. (1) Mobile units licensed in the Public Safety Pool may be installed in any vehicle which in an emergency would require cooperation and coordination with the licensee, and in any vehicle used in the performance, under contract, of official activities of the licensee. This provision does not permit the installation of radio units in non-emergency vehicles that are not performing governmental functions under contract but with which the li-censee might wish to communicate.

(2) Mobile units licensed under § 90.20(a)(2)(iii) may be installed in a ve-hicle or be hand-carried for use by any person with whom cooperation or co-ordinations is required for medical services activities.

(3) On the Interoperability Channels in the 700 MHz Public Safety Band (See § 90.531(b)(1)), hand-held and vehicular transmitters may be operated by any licensee holding a license in the 700 MHz Public Safety Band or by any li-censee holding a license for any other public safety frequency pursuant to part 90 of the Commission’s rules. Therefore, individual licenses are not required for hand-held and vehicular transmitters in the 700 MHz Band.

(b) Industrial/Business Pool. Mobile units licensed in the Industrial/Busi-ness Pool may be installed in vehicles of persons furnishing under contract to the licensee and for the duration of the contract, a facility or service directly related to the activities of the licensee.

(c) In addition to the requirements in paragraphs (a) and (b) of this section, frequencies assigned to licensees in the Private Land Mobile Radio Services may be installed in the facilities of those who assist the licensee in emer-gencies and with whom the licensee must communicate in situations in-volving imminent safety to life or property.

§ 90.423 Operation on board aircraft. (a) Except as provided in paragraphs

(b), (c), and (d) of this section, and ex-cept as may be provided in other sec-tions of this part with respect to oper-ation on specific frequencies, mobile stations first authorized after Sep-tember 14, 1973, under this part may be operated aboard aircraft for air-to-mo-bile, air-to-base, air-to-air and air-to- ship communications subject to the following:

(1) Operations are limited to aircraft that are regularly flown at altitudes below 1.6 km (1 mi) above the earth’s surface;

(2) Transmitters are to operate with an output power not to exceed ten watts;

(3) Operations are secondary to land- based systems;

(4) Such other conditions, including additonal reductions of altitude and power limitations, as may be required to minimize the interference potential to land-based systems.

(b) Exceptions to the altitude and power limitations set forth in para-graph (a) of this section may be au-thorized upon a showing of unusual operational requirements which justify departure from those standards, pro-vided that the interference potential to regular land-based operations would not be increased.

(c) Mobile operations aboard aircraft in the services governed by this part, under licenses in effect September 14, 1973, may be continued without regard to provisions of paragraph (a) of this section, as follows:

(1) Operations may be continued only for the balance of the term of such li-censes if aircraft involved are regularly flown at altitudes greater than 1.6 km (1 mi) above the earth’s surface.

(2) Operations may be continued for one additional renewal license term if the aircraft involved are regularly flown at altitudes below 1.6 km (1 mi) above the earth’s surface.

(d) Operation of radiolocation mobile stations may be authorized without re-gard to limitations and conditions set forth in paragraphs (a), (b), and (c) of this section.

§ 90.425 Station identification. Stations licensed under this part

shall transmit identification in accord-ance with the following provisions:

(a) Identification procedure. Except as provided for in paragraphs (d) and (e) of this section, each station or system shall be identified by the transmission of the assigned call sign during each transmission or exchange of trans-missions, or once each 15 minutes (30 minutes in the Public Safety Pool) dur-ing periods of continuous operation. The call sign shall be transmitted by voice in the English language or by International Morse Code in accord-ance with paragraph (b) of this section. If the station is employing either ana-log or digital voice scrambling, or non- voice emission, transmission of the re-quired identification shall be in the un-scrambled mode using A3E, F3E or G3E emission, or International Morse, with all encoding disabled. Permissible al-ternative identification procedures are as follows:

(1) A mobile relay stations call sign may be used to identify the associated control and mobile stations, except in the Public Safety Pool where the sta-tions operate on frequencies below 450 MHz. Alternatively, a base station (in-cluding a mobile relay station) which is controlled by radio may be identified by the transmission of the call sign of the station at which communications originate.

(2) One or more fixed relay stations may be identified by the transmission of the call signs of the stations at which the communications originate.

(3) When a mobile station transmits on a different frequency than its asso-ciated base station, the assigned call sign of either the mobile station or the base station may be transmitted. Fur-ther, a single mobile unit in the licens-ee’s authorized geographic area of oper-ation may transmit station identifica-tion on behalf of any other operating mobile units in the fleet.

(4) Use of an identifier other than the assigned call sign. (i) In the Public Safe-ty Pool, mobile units licensed to a gov-ernmental entity and which operate on frequencies above 30 MHz may use an identifier which contains, at a min-imum, the name of the licensee if the licensee maintains at the station a list

of the special identifiers to be used by the mobile units.

(ii) In the Industrial/Business Pool, licensees may request the Commis-sion’s local Engineer-in-Charge to ap-prove the use of special mobile unit identifiers in lieu of the assigned call sign. Such requests, however, will not be granted where it appears that harm-ful interference to international oper-ations may be caused by stations below 50 MHz, or by stations operating in areas within 80 km (50 miles) of an international boundary, or where it ap-pears that the proposed method of identification will not adequately dis-tinguish the mobile units of the appli-cant from the mobile units of other li-censees in the area.

(iii) In the Industrial/Business Pool, railroad licensees (as defined in § 90.7) may identify stations by the name of the railroad and the train number, ca-boose number, engine number, or the name of the fixed wayside station. If none of these forms is practicable, any similar name or number may be des-ignated by the railroad concerned for use by its employees in the identifica-tion of fixed points or mobile units, provided that a list of such identifiers is maintained by the railroad. An ab-breviated name or the initials of the railroad may be used where such are in general usage. In those areas where it is shown that no difficulty would be en-countered in identifying the trans-mission of a particular station (as, for example, where stations of one licensee are located in a yard isolated from other radio installations), approval may be given to a request from the li-censee for permission to omit the sta-tion identification.

(5) Use of identifiers in addition to as-signed call signs. Nothing in this section shall be construed as prohibiting the transmission of station or unit identi-fiers which may be necessary or desir-able for system operation, provided that they are transmitted in addition to the assigned station call sign or other permissible form of identifica-tion.

(b) Use of automatic Morse code identi-fication equipment. Automatically acti-vated equipment may be used to trans-mit station identification in Inter-national Morse Code pursuant to the following conditions:

(1) The signal output of the auto-matic identification equipment shall be connected to the transmitter at the microphone input or any other manu-facturer-provided signal input terminal and shall be adjusted to produce 40 per-cent ±10 percent of the maximum per-missible modulation or deviation level. This adjustment shall be performed when all other modulating signals are absent.

(2) The Morse code transmission rate shall be maintained between 20 and 25 words per minute.

(3) The frequency of the keyed tone comprising the identification signal shall be 1200 ±800 Hz. A licensee may be required to change the frequency in order to prevent interference to the op-erations of another co-channel li-censee.

(4) Should activation of automatic Morse code identification equipment interrupt the communications of an-other co-channel licensee, the Commis-sion may require the use of equipment which will delay automatic station identification until such co-channel communications are completed.

(c) Special provisions for identification in the Radiolocation Service. (1) Stations in the Radiolocation Service are not required to identify except upon spe-cific instruction from the Commission or as required by paragraph (c)(2) of this section.

(2) Stations in the Radiolocation Service operating on frequencies above 3400 kHz that employ spread spectrum techniques shall transmit a two letter manufacturer’s designator, authorized by the Commission on the station au-thorization, at the beginning and end-ing of each transmission and once every 15 minutes during periods of con-tinuing operation. The designator shall be transmitted in International Morse Code at a speed not exceeding 25 words per minute, and the spread spectrum mode of operation shall be maintained while the designator is being trans-mitted. The identifying signal shall be

clearly receivable in the demodulated audio of a narrow-band FM receiver.

(d) General exemptions. A station need not transmit identification if:

(1) It is a mobile station operating on the transmitting frequency of the asso-ciated base station.

(2) It is a mobile station in the Public Safety Pool using F1E or G1E emission.

(3) It is transmitting for telemetering purposes or for the activation of de-vices which are employed solely as a means of attracting attention, or for remote control purposes, or which is retransmitting by self-actuating means, a radio signal received from an-other radio station or stations.

(4) It is any type of radiopositioning or radar station authorized in a service other than the Radiolocation Service.

(5) It is used solely for automatic ve-hicle monitoring or location.

(6) It is a paging station authorized in accordance with the provisions of § 90.20(a)(2)(v).

(7) It is a mobile station employing non-voice emissions and the associated base station identifies on behalf of the mobile unit(s).

(8) It is a base or mobile station in the 220–222 MHz band authorized to op-erate on a nationwide basis in accord-ance with subpart T of this part.

(9) It is a wireless microphone station operating in accordance with the provi-sions of § 90.265(b).

(10) It is a Roadside Unit in a DSRCS system.

(e) Special provisions for stations li-censed under this part that are classi-fied as CMRS providers under part 20 of this chapter.

(1) Station identification will not be required for 929–930 MHz nationwide paging licensees or MTA or EA-based SMR licensees. All other CMRS sta-tions will be required to comply with the station identification requirements of this paragraph.

(2) CMRS stations subject to a sta-tion identification requirement will be permitted to use a single call sign for commonly owned facilities that are op-erated as part of a single system. The call sign must be transmitted each hour within five minutes of the hour, or upon completion of the first trans-mission after the hour.

§ 90.429 Control point and dispatch point requirements.

(a) Control point required. Unless per-mitted to be operated on an unattended basis, each station shall be provided with a control point;

(b) A control point is an operating position:

(1) Which must be under the control and supervision of the licensee;

(2) Where a person immediately re-sponsible for the operation of the transmitter is stationed;

(3) Where the monitoring facilities required by this part are installed.

(c) Control point location. The location of the control point will be specified in the station license and will be assumed to be the same as that of the transmit-ting equipment unless an application for a different location has been ap-proved by the Commission.

(d) Control point facilities required. At each control point, the following facili-ties shall be installed:

(1) A carrier-operated device which will provide continuous visual indica-tion when the transmitter is radiating, or, a pilot lamp or meter which will provide continuous visual indication when the transmitter circuits have been placed in a condition to produce radiation. The provisions of this sub-paragraph shall not apply to hand-car-ried transmitters or transmitters in-stalled on motorcycles. The control point for a transmitter utilized to acti-vate another radio station may employ a single pilot lamp or meter as an indi-cation of the activation of local and re-mote transmitters.

(2) Facilities which will permit the person responsible for the operation of the transmitter either to disconnect the dispatch point circuits from the transmitter or to render the trans-mitter inoperative from any dispatch point under his supervision; and

(3) Facilities which will permit the person responsible for the operation of the transmitter to turn the trans-mitter carrier on and off at will.

(e) Dispatch point. A dispatch point is any position from which messages may be transmitted under the supervision of the person at a control point who is re-sponsible for the operation of the transmitter. Dispatch points may be installed without authorization from the Commission.

Subpart O—Transmitter Control

§ 90.460 Scope. This subpart sets forth the provisions

relating to permissible methods of transmitter control and interconnec-tion (see the definition in § 90.7) of radio systems authorized under this part.


§ 90.461 Direct and remote control of transmitters.

(a) In general. Radio transmitters may be operated and controlled di-rectly (as when the operating position for the transmitter and the trans-mitter being operated are at the same location), or remotely (as when the transmitter being operated and the po-sition from which it is being operated are at different locations).

(b) Control of transmitters at remote lo-cations. Radio transmitters at remote locations may be operated and con-trolled through the use of wire line or radio links; or through dial-up circuits, as provided in paragraph (c) of this sec-tion. Such control links or circuits may be either those of the licensee or they may be provided by common car-riers authorized by law to furnish such service.

(c) Dial-up circuits. Dial-up circuits may be provided by wire line telephone companies under appropriate tariffs, and they may be used by licensees for purposes of transmitter control, pro-vided:

(1) The dial-up circuits serve only to link licensed transmitter control points and the transmitters being con-trolled.

(2) The dial-up circuits are so de-signed that the transmitters being con-trolled cannot be operated from any fixed position other than the licensed control points for those transmitters.

(3) Equipment used to provide the transmitter/dial-up-circuit interface is designed to preclude associated mobile units of the licensee from reaching any point(s) served by the wire line tele-phone facilities other than the control point(s) of the station(s) controlled.

(4) Any direct electrical connection to the telephone network shall comply with applicable tariffs and with part 68 of the Commission’s Rules (See § 90.5(j)).

(5) Interconnection, within the mean-ing of §§ 90.7 and 90.477 through 90.483, may not take place at a control point which connects to its associated trans-mitter(s) through dial-up circuits; nor may such dial-up transmitter control

§ 90.463 Transmitter control points. (a) A control operator is required to

be stationed at the operating position of a transmitter control point. A con-trol operator is any person designated by the licensee to exercise supervision and control over the operation and use of the licensee’s facilities. The control operator may be the licensee; or an em-ployee of the licensee; or the agent of the licensee, appointed by the licensee to act as the control operator; or a third-party contractor, engaged by the licensee to serve as the control oper-ator: Provided, however, In no case, through appointment or designation of any person to serve as control oper-ator, may the licensee delegate any of the duties and responsibilities the li-censee may have in his capacity as li-censee.

(b) Each station or licensed system of communication shall normally have a control point, or control points, at which the control operator or opera-tors are stationed and at or from which the licensee may exercise supervision and control over the authorized facili-ties, as required by the provisions of § 90.461. Provided, however, Control point requirements may vary from one system to another, depending upon the nature of the radio operation; the way and by whom the facilities are em-ployed; and other factors, as set out in other rule sections under this subpart.

(c) A transmitter control point may be located at a fixed position in a sys-tem of communication at or from which the control operator exercises supervision and control over the oper-ation and use of the licensed facilities. Each fixed transmitter control point shall have equipment and facilities to permit the control operator:

(1) To determine when the trans-mitter or transmitters controlled are either radiating ‘‘RF’’ energy, or when the transmitter circuits have been placed in a condition to produce such radiation. This may be accomplished either through the use of a carrier op-erated device which provides a visual

indication when the transmitter(s) are radiating or a pilot lamp or meter which provides a visual indication when the transmitter circuits have been placed in a condition to produce radiation. Further, where a local trans-mitter is used to activate a remote transmitter or transmitters in the li-censee’s system of communication, a single pilot lamp or meter may be em-ployed to indicate the activation of both the local and the remote trans-mitter(s).

(2) To turn the carrier of the trans-mitter on and off at will, or to close the system down completely, when cir-cumstances warrant such action.

(d) The licensee’s transmitting facili-ties may be operated from dispatch points, the fixed control point shall have equipment to permit the control operator to either disconnect the dis-patch point circuits from the trans-mitter(s) or to render the trans-mitter(s) inoperative from any dis-patch point being supervised.

(e) Where the system is inter-connected with public communication facilities, as provided at §§ 90.477 through 90.483, and where those rules so require, the fixed control point shall be equipped to permit the control oper-ator:

(1) To monitor co-channel facilities of other licensees sharing an assigned channel or channels with the licensee in the licensee’s area of operation; and,

(2) To terminate any transmission(s) or communication(s) between points in the public communications system and the private communications system.

(f) In urban areas, the location of fixed transmitter control points will be specified, ‘‘same as transmitter,’’ un-less the control point is at a street ad-dress which is different from that of the transmitter(s) controlled. In rural areas, the location of fixed control points will be specified, ‘‘same as transmitter,’’ unless the control point is more than 152.5 m (500 ft) from the transmitter(s) controlled. In the latter case, the approximate location of the control point will be specified in dis-tance and direction from the trans-mitter(s) controlled in terms of dis-tance and geographical quadrant, re-spectively. It would be assumed that the location of a fixed control point is

the same as the location of the trans-mitter(s) controlled, unless the appli-cant includes a request for a different location described in appropriate terms as indicated herein.

(g) [Reserved] (h) Mobile transmitters shall be as-

sumed to be under the immediate con-trol of the mobile operator; provided, however, overall supervision and con-trol of the operation and use of a com-munication system may be the respon-sibility of a fixed control point oper-ator. In general, mobile transmitters shall be equipped to permit the oper-ator to determine when they are radi-ating ‘‘RF’’ energy or when the trans-mitter circuits have been placed in a condition to produce such radiation. This may be accomplished either through the use of a carrier operated device or of a pilot lamp or meter which will provide a visual indication when the transmitter is radiating or has been placed in a condition to produce radiation provided, however, that hand-carried or pack-carried transmitters and transmitters in-stalled on motorcycles need not be so equipped.

§ 90.465 Control of systems of commu-nication.

(a) Depending on design consider-ations, control of a system of commu-nication may be exercised in varying ways. In single frequency simplex, base/mobile operations, control may be exercised by the control operator at the fixed control point. In mobile relay systems, where there is an associated control point or control station, con-trol may be exercised by the operator at the control point or control station. In mobile-only systems, control may be exercised by the mobile operator. In communication systems involving mul-tiple base stations or fixed relays con-trol of the system may result from a combination of factors and consider-ations, including control by a fixed control point operator at some point within the system of communication or

control by the mobile station operator of the licensee.

(b) In internal systems, as defined in § 90.7, control may be maintained by conforming the system to the require-ments of §§ 90.471 through 90.475.

(c) In interconnected systems, as de-fined in § 90.7, control may be main-tained by conforming operation and system design to that permitted in §§ 90.477 through 90.483.

[43 FR 54791, Nov. 22, 1978, as amended at 54 FR 39740, Sept. 28, 1989; 72 FR 35199, June 27, 2007]

§ 90.467 Dispatch points.

Dispatch points meeting the require-ments of this section need not be spe-cifically authorized; provided, however, that the licensee of any radio station operated from a dispatch point or points shall assume full responsibility for the use and operation of the author-ized facilities in compliance with all applicable provisions of law or rule and shall comply with the policy:

(a) A dispatch point may be linked to the transmitter(s) being operated by private or leased wire line of fixed radio circuits, provided the require-ments of § 90.463 are met.

(b) No telephone position in the pub-lic, switched, telephone network will be treated as a dispatch point within the meaning or intent of this section.

(c) Operation of transmitting facili-ties from dispatch points is permitted only when the control operator at a fixed control point in the system is on duty and at no other time.

§ 90.469 Unattended operation.

(a) Subject to the provisions of §§ 90.243, 90.245, and 90.247, mobile relay, fixed relay, and mobile repeater sta-tions are authorized for unattended op-eration; and the transmitter control point requirements set out at §§ 90.463 through 90.465 shall not apply.

(b) Self-activated transmitters may be authorized for unattended operation where they are activated by either electrical or mechanical devices, pro-vided the licensee adopts reasonable means to guard against malfunctions and harmful interference to other users.

INTERNAL TRANSMITTER CONTROL SYSTEMS

§ 90.471 Points of operation in internal transmitter control systems.

The transmitting facilities of the li-censee may be operated from fixed po-sitions located on premises controlled by the licensee. The fixed position may be part of a private telephone exchange or it may be any position in a closed or limited access communications facility intended to be used by employees of the licensee for internal communica-tions and transmitter control purposes. Operating positions in internal trans-mitter control systems are not synony-mous with dispatch points (See § 90.467) nor with telephone positions which are part of the public, switched telephone network; and the scheme of regulation is to be considered and treated as being different. See §§ 90.485 through 90.489.

[44 FR 67125, Nov. 23, 1979]

§ 90.473 Operation of internal trans-mitter control systems through li-censed fixed control points.

An internal transmitter control sys-tem may be operated under the control and supervision of a control operator stationed at a fixed control point in the system. In such a case, the control point must be equipped to permit the control operator to monitor all traffic to and from fixed positions and mobile stations or paging units of the licensee; and the system shall be so designed to permit the control operator to either disconnect any operating position in the internal system from the trans-mitter control circuit or to close the system down entirely at will.

[44 FR 67125, Nov. 23, 1979]

§ 90.475 Operation of internal trans-mitter control systems in specially equipped systems.

(a) An internal transmitter control system need not be designed to meet the requirements of § 90.473 if it meets the following requirements:

(1) All operating positions must be located on premises controlled by the licensee.

(2) An internal transmitter control system may be used in conjunction with other approved methods of trans-mitter control and interconnection so

long as the internal transmitter con-trol system, itself, is neither accessed from telephone positions in the public switched telephone network (PSTN), nor uses dial-up circuits in the PSTN. Licensees with complex communica-tions systems involving fixed systems whose base stations are controlled by such systems may automatically ac-cess these base stations through the microwave or operational fixed sys-tems from positions in the PSTN, so long as the base stations and mobile units meet the requirements of § 90.483 and if a separate circuit is provided for each mode of transmitter operation (i.e., conventional, dial-up or Internet).

(3) The system must be designed so that upon completion of a trans-mission, the base station trans-mitter(s) will close down automati-cally within 3 seconds.

(4) To guard against malfunctions, the system must also be designed so that the base station(s) will be deacti-vated by an automatic timing device when a modulated signal is not trans-mitted for a period of three (3) consecu-tive minutes.

(5) The system must include auto-matic monitoring equipment, installed at the base station transmitter site(s), which will prevent the activation of the system when signals of other co- channel stations are present.

(b) [Reserved]

§ 90.477 Interconnected systems. (a) Applicants for new land stations

to be interconnected with the public switched telephone network must indi-cate on their applications (class of sta-tion code) that their stations will be interconnected. Licensees of land sta-tions that are not interconnected may interconnect their stations with the public switched telephone network only after modifying their license. See § 1.929 of this chapter. In all cases a de-tailed description of how interconnec-tion is accomplished must be main-tained by licensees as part of their sta-tion records. See § 90.433 of this part.

(b) In the frequency ranges 806–824 MHz, 851–869 MHz, 896–901 MHz, and 935– 940 MHz, interconnection with the pub-lic switched telephone network is au-thorized under the following condi-tions:

(1) Interconnected operation is on a secondary basis to dispatch operation. This restriction will not apply to trunked systems or on any channel as-signed exclusively to one licensee.

(2) Interconnection may be accom-plished at any location through a sepa-rate or shared interconnection device. When land stations subject to this part are multiple licensed or shared by au-thorized users, arrangements for tele-phone service must be made with a duly authorized carrier by users, li-censees, or their authorized agents on a non-profit cost sharing basis. When telephone service costs are shared, at least one licensee participating in the cost sharing arrangement must main-tain cost sharing records and the costs must be distributed at least once a year. Licensees, users, or their author-ized agents may also make joint use ar-rangements with a duly authorized car-rier and arrange that each licensee or user pay the carrier directly for the li-censee’s or user’s share of the joint use

of the shared telephone service. A re-port of the cost distribution must be placed in the licensee’s station records and made available to participants in the sharing and the Commission upon request. In all cases, arrangements with the duly authorized carrier must disclose the number of licensees and users and the nature of the use.

(c) Interconnection of facilities in the Radiolocation Service (subpart F) will not be permitted.

(d) In the frequency ranges below 800 MHz, interconnection with the public switched telephone network is author-ized under the following conditions:

(1) Interconnected operation is on a secondary basis to dispatch operation. This restriction will not apply to trunked systems or on any channel as-signed exclusively to one licensee.

(2) Interconnection may be accom-plished at any location through a sepa-rate or shared interconnection device. When land stations subject to this part are multiple licensed or shared by au-thorized users, arrangements for tele-phone service must be made with a duly authorized carrier by users, li-censees, or their authorized agents on a non-profit cost sharing basis. When telephone service costs are shared, at least one licensee participating in the cost sharing arrangement must main-tain cost sharing records and the costs must be distributed at least once a year. Licensees, users, or their author-ized agents may also make joint use ar-rangements with a duly authorized car-rier and arrange that each licensee or user pay the carrier directly for the li-censee’s or user’s share of the joint use of the shared telephone service. A re-port of the cost distribution must be placed in the licensee’s station records and made available to participants in the sharing and the Commission upon request. In all cases, arrangements with the duly authorized carrier must disclose the number of licensees and users and the nature of the use.

(3) For licensees in the Industrial/ Business Pool and those licensees who establish eligibility pursuant to § 90.20(a)(2) of this part, except for §§ 90.20(a)(2)(i) and 90.20(a)(2)(ii) of this part and medical emergency systems in the 450–470 MHz band, interconnection will be permitted only where the base

station site or sites proposed stations are located 120 km (75 mi.) or more from the designated centers of the ur-banized areas listed below. If these li-censees seek to connect within 120 km (75 mi.) of the 25 cities, they must ob-tain the consent of all co-channel li-censees located both within 120 km (75 mi.) of the center of the city; and with-in 120 km (75 mi.) of the interconnected base station transmitter. The consen-sual agreements among the co-channel licensees must specifically state the terms agreed upon and a statement must be submitted to the Commission indicating that all co-channel licensees have consented to the use of inter-connection. If a licensee has agreed to the use of interconnection on the chan-nel, but later decides against the use of interconnection, the licensee may re-quest that the co-channel licensees re-consider the use of interconnection. If the licensee is unable to reach an agreement with co-channel licensees, the licensee may request that the Com-mission consider the matter and assign it to another channel. If a new licensee is assigned to a frequency where all the co-channel licensees have agreed to the use of interconnection and the new li-censee does not agree, the new licensee may request that the co-channel li-censees reconsider the use of inter-connection. If the new licensee cannot reach an agreement with co-channel li-censees it may request that the Com-mission reassign it to another channel.

§ 90.483 Permissible methods and re-quirements of interconnecting pri-vate and public systems of commu-nications.

Interconnection may be accom-plished by commercial mobile service providers licensed under this part by any technically feasible means. Inter-connection may be accomplished by private mobile service providers either manually or automatically under the supervision and control of a trans-mitter control operator at a fixed posi-tion in the authorized system of com-munications or it may be accomplished under the supervision and control of mobile operators, and is subject to the following provisions:

(a) Where a system is interconnected manually at a fixed control point, the control point operator must maintain the capability to turn the carrier of the transmitter off or to de-activate the system completely when circumstances warrant such action.

(b) When the system is inter-connected automatically it may be su-pervised at the control point or in mo-bile units.

(1) For control point supervision, the following is required:

47 CFR Ch. I (10–1–10 Edition) § 90.483

(i) The control point operator must maintain the capability to turn the carrier of the transmitter off or to deactivate the system completely when circumstances warrant such action.

(ii) When a frequency is shared by more than one system, automatic mon-itoring equipment must be installed at the base station to prevent activation of the transmitter when signals of co- channel stations are present and acti-vation would interfere with commu-nications in progress. Licensees may operate without the monitoring equip-ment if they have obtained the consent of all co-channel licensees located within a 120 kilometer (75 mile) radius of the interconnected base station transmitter. A statement must be sub-mitted to the Commission indicating that all co-channel licensees have con-sented to operate without the moni-toring equipment. If a licensee has agreed that the use of monitoring equipment is not necessary, but later decides that the monitoring equipment is necessary, the licensee may request that the co-channel licensees recon-sider the use of monitoring equipment. If the licensee cannot reach an agree-ment with co-channel licensees, the li-censee may request that the Commis-sion consider the matter and assign it to another channel. If a new licensee is assigned to a frequency where all the co-channel licensees have agreed that the use of monitoring equipment is not necessary, and the new licensee does not agree, the new licensee may re-quest the co-channel licensees to re-consider the use of monitoring equip-ment. If the new licensee cannot reach an agreement with co-channel licens-ees, it should request a new channel from the Commission. Systems on fre-quencies above 800 MHz are exempt from this requirement.

(2) For mobile unit supervision, the following is required:

(i) When a frequency is shared by more than one system, automatic mon-itoring equipment must be installed at the base station to prevent activation of the transmitter when signals of co- channel stations are present and acti-vation would interfere with commu-nications in progress. Licensees may operate without this equipment if they have obtained the consent of all co-

channel licensees located within a 120 kilometer (75 mile) radius of the inter-connected base station transmitter. A statement must be submitted to the Commission indicating that all co- channel licensees have consented to op-erate without the monitoring equip-ment. If a licensee has agreed that the use of monitoring equipment is not necessary, but later decides that the monitoring equipment is necessary, the licensee may request that the co-chan-nel licensees reconsider the use of mon-itoring equipment. If the licensee can-not reach an agreement with co-chan-nel licensees, the licensee may request that the Commission consider the mat-ter and assign it to another channel. If a new licensee is assigned to a fre-quency where all the co-channel licens-ees have agreed that the use of moni-toring equipment is not necessary, and the new licensee does not agree, the new licensee may request the co-chan-nel licensees to reconsider the use of monitoring equipment. If the new li-censee cannot reach an agreement with co-channel licensees, it should request a new channel from the Commission. Systems on frequencies above 800 MHz are exempt from this requirement.

(ii) Initial access points within the public switched telephone network must be limited to transmission of a 3- second tone, after which time the transmitter shall close down. No addi-tional signals may be transmitted until acknowledgement from a mobile sta-tion of the licensee is received. Licens-ees are exempt from this requirement if they have obtained the consent of all co-channel licensees located within a 120 kilometer (75 mile) radius of the interconnected base station trans-mitter. However, licensees may choose to set their own time limitations. A statement must be submitted to the Commission indicating that all co- channel licensees have consented to op-erate without the monitoring equip-ment. If a licensee has agreed that the use of monitoring equipment is not necessary, but later decides that the monitoring equipment is necessary, the licensee may request that the co-chan-nel licensees reconsider the use of mon-itoring equipment. If the licensee can-not reach an agreement with co-chan-nel licensees, the licensee may request

that the Commission consider the mat-ter and assign it to another channel. If a new licensee is assigned to a fre-quency where all the co-channel licens-ees have agreed that the use of moni-toring equipment is not necessary, and the new licensee does not agree, the new licensee may request the co-chan-nel licensees to reconsider the use of monitoring equipment. If the new li-censee cannot reach an agreement with co-channel licensees, it should request a new channel from the Commission. Systems on frequencies above 800 MHz are exempt from this requirement.

(c) In single frequency systems, equipment must be installed at the base station which will limit any single transmission from within the public switched telephone network to 30 sec-onds duration and which in turn will activate the base station receiver to monitor the frequency for a period of not less than three (3) seconds. The mo-bile station must be capable of termi-nating the communications during the three (3) seconds. Licensees are exempt from this requirement if they have ob-tained the consent of all co-channel li-censees located within a 120 km (75 mile) radius of the interconnected base station transmitter. However, licensees may choose to set their own time limi-tations. A statement must be sub-mitted to the Commission indicating that all co-channel licensees have con-sented to operate without the moni-toring equipment. If a licensee has agreed that the use of monitoring equipment is not necessary, but later decides that the monitoring equipment is necessary, the licensee may request that the co-channel licensees recon-sider the use of monitoring equipment. If the licensee cannot reach an agree-ment with co-channel licensees, the li-censee may request that the Commis-sion consider the matter and assign it another channel. If a new licensee is assigned to a frequency where all the co-channel licensees have agreed that the use of monitoring equipment. If the new licensee cannot reach an agree-ment with co-channel licensees, it should request a new channel from the Commission.

(d) A timer must be installed at the base station transmitter which limits communications to three (3) minutes.

After three (3) minutes, the system must close down, with all circuits be-tween the base station and the public switch telephone network discon-nected. This provision does not apply to systems which establish eligibility pursuant to §§ 90.20(a)(1)(i), 90.20(a)(1)(ii), and 90.20(a)(2), except §§ 90.20(a)(2)(i) and 90.20(a)(2)(ii), or who are Power, Petroleum, or Railroad li-censees (as defined in § 90.7), or to sys-tems above 800 MHz. All systems must be equipped with a timer that closes down the transmitter within three minutes of the last transmission. Li-censees may operate without these re-quirements if they have obtained the consent of all co-channel licensees lo-cated within a 120 km (75 mile) radius of the interconnected base station transmitter. However, licensees may choose to set their own time limita-tions. A statement must be submitted to the Commission indicating that all co-channel licensees have consented to operate without the monitoring equip-ment. If a licensee has agreed that the use of monitoring equipment is not necessary, but later decides that the monitoring equipment is necessary, the licensee may request that the co-chan-nel licensees reconsider the use of mon-itoring equipment. If the licensee can-not reach an agreement with co-chan-nel licensees, the licensee may request that the Commission consider the mat-ter and assign it to another channel. If a new licensee is assigned to a fre-quency where all the co-channel licens-ees have agreed that the use of moni-toring equipment is not necessary, and the new licensee does not agree, the new licensee may request the co-chan-nel licensees to reconsider the use of monitoring equipment. If the new li-censee cannot reach an agreement with co-channel licensees, it should request a new channel from the Commission.

Subpart P—Paging Operations

§ 90.490 One-way paging operations in the private services.

(a) Subject to specific prohibition or restriction by rule provisions gov-erning the radio service in which a li-censee’s radio system is authorized, paging operations are permitted:

(1) Where the signals and messages are transmitted by a control operator of the licensee stationed at a licensed control point in the licensee’s system of communication.

(2) Where the signals and messages are transmitted from an operating po-sition within an internal system of communication which meets the tests of §§ 90.471 through 90.475.

(3) Where the signals and messages are transmitted from a dispatch point within the licensee’s system of commu-nication, as defined as § 90.7.

(b) Systems employing dial-up cir-cuits (§ 90.461(c)) may be used in one- way paging operations, but only where the paging signals are transmitted as provided at paragraph (a)(1) of this sec-tion.

(c) Paging may be initiated directly from telephone positions in the public switched telephone network. When land stations are multiple licensed or otherwise shared by authorized users, arrangements for the telephone service must be made with a duly authorized carrier by users, licensees, or their au-thorized agents on a non-profit, cost- shared basis. When telephone service costs are shared, at least one licensee participating in the cost sharing ar-rangements must maintain cost shar-ing records and the costs must be dis-tributed at least once a year. Licens-ees, users, or their authorized agents may also make joint use arrangements with a duly authorized carrier and ar-range that each licensee or user pay the carrier directly for the licensee’s or user’s share of the joint use of the shared telephone service. A report of the cost distribution must be placed in the licensee’s station records and made available to participants in the sharing arrangement and the Commission upon request. In all cases, arrangements with the duly authorized carrier must

disclose the number of licensees and users and the nature of the use.

[47 FR 39509, Sept. 8, 1982, as amended at 48 FR 56231, Dec. 20, 1983; 52 FR 15501, Apr. 29, 1987]

(b) License applications for Inter-operability channels in the 769–775 MHz and 799–805 MHz frequency bands must be approved by a state-level agency or organization responsible for admin-istering state emergency communica-tions. States may hold the licenses for Interoperability channels or approve other qualified entities to hold such li-censes. States may delegate the ap-proval process for interoperability channels to another entity, such as re-gional planning committees.

[72 FR 48860, Aug. 24, 2007]

§ 90.527 Regional plan requirements. Each regional planning committee

must submit a regional plan for ap-proval by the Commission.

(a) Common elements. Regional plans must incorporate the following com-mon elements:

(1) Identification of the document as the regional plan for the defined region with the names, business addresses, business telephone numbers, and orga-nizational affiliations of the chair-persons and all members of the plan-ning committee.

(2) A summary of the major elements of the plan and an explanation of how all eligible entities within the region were given an opportunity to partici-pate in the planning process and to have their positions heard and consid-ered fairly.

(3) A general description of how the spectrum would be allotted among the various eligible users within the region with an explanation of how the require-ments of all eligible entities within the region were considered and, to the de-gree possible, met.

(4) An explanation as to how needs were assigned priorities in areas where not all eligible entities could receive li-censes.

(5) An explanation of how the plan had been coordinated with adjacent re-gions.

(6) A detailed description of how the plan put the spectrum to the best pos-sible use by requiring system design with minimum coverage areas, by as-signing frequencies so that maximum

frequency reuse and offset channel use may be made, by using trunking, and by requiring small entities with mini-mal requirements to join together in using a single system where possible.

(7) A detailed description of the fu-ture planning process, including, but not limited to, amendment process, meeting announcements, data base maintenance, and dispute resolution.

(8) A certification by the regional planning chairperson that all planning committee meetings, including sub-committee or executive committee meetings, were open to the public.

(b) Modification of regional plans. Re-gional plans may be modified by sub-mitting a written request, signed by the regional planning committee, to the Chief, Wireless Telecommuni-cations Bureau. The request must con-tain the full text of the modification, and must certify that successful co-ordination of the modification with all adjacent regions has occurred and that all such regions concur with the modi-fication.

§ 90.528 Public safety broadband li-cense.

(a) The 763–768/793–798 MHz bands are allocated on a nationwide basis for public safety broadband operations and licensed to a single Public Safety Broadband Licensee. The 768–769/798–799 MHz bands also are licensed to the Public Safety Broadband Licensees as guard bands. The license area of the Public Safety Broadband License con-sists of the contiguous 48 states, Alas-ka, Hawaii, Gulf of Mexico, and the U.S. territories.

(b) The Public Safety Broadband Li-cense authorizes construction and op-eration of base stations anywhere with-in the area authorized by the license, except as follows:

(1) A station is required to be individ-ually licensed if:

(i) International agreements require coordination;

(ii) Submission of an environmental assessment is required under § 1.1307 of this chapter; or

(iii) The station would affect areas identified in § 1.924 of this chapter.

(2) Any antenna structure that re-quires notification to the Federal Avia-tion Administration (FAA) must be

registered with the Commission prior to construction under § 17.4 of this chapter.

(c) Mobile and portable devices may operate without individual license under the authority of the Public Safe-ty Broadband License.

(d) The term of the Public Safety Broadband License shall not exceed ten years from June 13, 2009. The Public Safety Broadband Licensee is entitled to a renewal expectancy barring viola-tions of law, rules or policy warranting denial of renewal.

(e) The Public Safety Broadband Li-cense may not be partitioned or disaggregated.

(f) The Public Safety Broadband Li-censee may not voluntarily assign or transfer control of the Public Safety Broadband License.

(g) Quarterly reporting of financial and operational information. The Public Safety Broadband Licensee shall sub-mit, on a quarterly basis, a full finan-cial accounting to the Commission, in a format to be set forth in the Network Sharing Agreement, and as approved by the Commission. Such quarterly fi-nancial reports shall be filed with the Commission, with a copy to the Chiefs of the Wireless Telecommunications and the Public Safety and Homeland Security Bureaus.

§ 90.529 State License. (a) Narrowband channels designated

as state channels in § 90.531 are licensed to each state (as defined in § 90.7) as fol-lows:

(1) Each state that chooses to take advantage of the spectrum designated as state channels must file an applica-tion for up to 2.4 megahertz of this spectrum no later than December 31, 2001. For purposes of this section, the elected chief executive (Governor) of each state, or his or her designee, shall be deemed the person authorized to apply for the State License.

(2) What ever part of this 2.4 mega-hertz that a state has not applied for by December 31, 2001, will revert to General Use and be administered by the relevant RPC (or RPCs in the in-stances of states that encompass mul-tiple RPCs).

(b) Each state license will be granted subject to the condition that the state certifies on or before each applicable benchmark date that it is:

(1) providing or prepared to provide ‘‘substantial service’’ to one-third of their population or territory by Janu-ary 1, 2012, i.e., within five years of the date that incumbent broadcasters are required to relocate to other portions of the spectrum;

(2) providing or prepared to provide ‘‘substantial service’’ to two-thirds of their population or territory by Janu-ary 1, 2017, i.e., within ten years of the date that incumbent broadcasters are required to relocate to other portions of the spectrum.

(c) The Commission will deem a state ‘‘prepared to provide substantial serv-ice’’ if the licensee certifies that a radio system has been approved and funded for implementation by the deadline date. ‘‘Substantial service’’ refers to the construction and oper-ation of 700 MHz facilities by public safety entities providing service which is sound, favorable , and substantially above a level of mediocre service which just might minimally warrant renewal.

(d) If a state licensee fails to meet any condition of the grant the state li-cense is modified automatically to the frequencies and geographic areas where the state certifies that it is providing substantial service.

(e) Any recovered state license spec-trum will revert to General Use. How-ever, spectrum licensed to a state under a state license remains unavail-able for reassignment to other appli-cants until the Commission’s database reflects the parameters of the modified state license.

are designated to public safety eligi-bles subject to Commission approved regional planning committee regional plans. Voice operations on these chan-nels are subject to compliance with the spectrum usage efficiency require-ments set forth in § 90.535(d).

(7) Secondary trunking channels. The following channel pairs are reserved for secondary trunking operations: 21/981, 22/982, 101/1061, 102/1062, 181/1141, 182/1142, 261/1221, 262/1222, 659/1619, 660/1620, 739/ 1699, 740/1700, 819/1779, 820/1780, 899/1859, and 900/1860. They may be used only in combination with the appropriate adja-cent Interoperability channel pairs specified in paragraph (b)(1)(iii) of this section in trunked systems.

(c) [Reserved] (d) Combining channels. Except as

noted in this section, at the discretion of the appropriate regional planning committee, contiguous channels may be used in combination in order to ac-commodate requirements for larger bandwidth emissions, in accordance with this paragraph. Interoperability channels may not be combined with channels in another group except for channels for secondary trunking chan-nels.

(1) Narrowband. Subject to compli-ance with the spectrum usage effi-ciency requirements set forth in § 90.535, two or four contiguous narrowband (6.25 kHz) channels may be used in combination as 12.5 kHz or 25 kHz channels, respectively. The lower (in frequency) channel for two channel combinations must be an odd (i.e., 1, 3, 5 * * *) numbered channel. The lowest (in frequency) channel for four channel combinations must be a channel whose number is equal to 1+(4xn), where n = any integer between 0 and 479, inclu-sive (e.g., channel number 1, 5, * * * 1917). Channel combinations are des-ignated by the lowest and highest channel numbers separated by a hy-phen, e.g., ‘‘1–2’’ for a two channel com-bination and ‘‘1–4’’ for a four channel combination.

(2) [Reserved] (e) Channel pairing. In general, chan-

nels must be planned and assigned in base/mobile pairs that are separated by 30 MHz. However, until December 31, 2006, channels other than those listed in paragraphs (b)(1) and (c)(1), may be

planned and assigned in base/mobile pairs having a different separation, where necessary because 30 MHz base/ mobile pairing is precluded by the pres-ence of one or more co-channel or adja-cent channel TV/DTV broadcast sta-tions.

(f) Internal guard band. The internal guard band (768–769/798–799 MHz) is re-served.

(g) Broadband. The 763–768 MHz and 793–798 MHz bands are allocated for broadband communications pursuant to the Public Safety Broadband Li-cense.

only during time slots when the trans-mitter is active. All measurements are made at the transmitter’s output port. If a transmitter has an integral an-tenna, a suitable power coupling device shall be used to couple the RF signal to the measurement instrument. The cou-pling device shall substantially main-tain the proper transmitter load im-pedance. The ACP measurements may be made with a spectrum analyzer ca-pable of making direct ACP measure-ments. ‘‘Measurement bandwidth’’, as used for non-swept measurements, im-plies an instrument that measures the power in many narrow bandwidths equal to the nominal resolution band-width and integrates these powers to determine the total power in the speci-fied measurement bandwidth.

(1) Setting reference level. Set trans-mitter to maximum output power. Using a spectrum analyzer capable of ACP measurements, set the measure-ment bandwidth to the channel size. For example, for a 6.25 kHz transmitter set the measurement bandwidth to 6.25 kHz. Set the frequency offset of the measurement bandwidth to zero and adjust the center frequency of the in-strument to the assigned center fre-quency to measure the average power level of the transmitter. Record this power level in dBm as the ‘‘reference power level.’’

(2) Non-swept power measurement. Using a spectrum analyzer capable of ACP measurements, set the mesurement bandwidth and frequency offset from the assigned center fre-quency as shown in the tables in § 90.543 (a) above. Any value of resolution bandwidth may be used as long as it does not exceed 2 percent of the speci-fied measurement bandwidth. Measure the power level in dBm. These meas-urements should be made at maximum power. Calculate ACP by substracting the reference power level measured in (b)(1) from the measurements made in this step. The absolute value of the cal-culated ACP must be greater than or equal to the absolute value of the ACP given in the table for each condition above.

(3) Swept power measurement. Set a spectrum analyzer to 30 kHz resolution bandwidth, 1 MHz video bandwidth and average, sample, or RMS detection. Set

the reference level of the spectrum an-alyzer to the RMS value of the trans-mitter power. Sweep above and below the carrier frequency to the limits de-fined in the tables. Calculate ACP by substracting the reference power level measured in (b)(1) from the measure-ments made in this step. The absolute value of the calculated ACP must be greater than or equal to the absolute value of the ACP given in the table for each condition above.

(c) Out-of-band emission limit. On any frequency outside of the frequency ranges covered by the ACP tables in this section, the power of any emission must be reduced below the mean out-put power (P) by at least 43 + 10log (P) dB measured in a 100 kHz bandwidth for frequencies less than 1 GHz, and in a 1 MHz bandwidth for frequencies greater than 1 GHz.

(d) Authorized bandwidth. Provided that the ACP requirements of this sec-tion are met, applicants may request any authorized bandwidth that does not exceed the channel size.

(e) For operations in the 763–768 MHz and the 793–798 MHz bands, the power of any emission outside the licensee’s fre-quency band(s) of operation shall be at-tenuated below the transmitter power (P) within the licensed band(s) of oper-ation, measured in watts, in accord-ance with the following:

(1) On all frequencies between 769–775 MHz and 799–805 MHz, by a factor not less than 76 + 10 log (P) dB in a 6.25 kHz band segment, for base and fixed sta-tions.

(2) On all frequencies between 769–775 MHz and 799–805 MHz, by a factor not less than 65 + 10 log (P) dB in a 6.25 kHz band segment, for mobile and portable stations.

(3) Compliance with the provisions of paragraphs (e)(1) and (2) of this section is based on the use of measurement in-strumentation such that the reading taken with any resolution bandwidth setting should be adjusted to indicate spectral energy in a 6.25 kHz segment.

(f) For operations in the 763–775 MHz and 793–805 MHz bands, all emissions including harmonics in the band 1559– 1610 MHz shall be limited to -70 dBW/ MHz equivalent isotropically radiated power (EIRP) for wideband signals, and -80 dBW EIRP for discrete emissions of

less than 700 Hz bandwidth. For the purpose of equipment authorization, a transmitter shall be tested with an an-tenna that is representative of the type that will be used with the equipment in normal operation.

(g) When an emission outside of the authorized bandwidth causes harmful interference, the Commission may, at its discretion, require greater attenu-ation than specified in this section.

§ 90.545 TV/DTV interference protec-tion criteria.

Public safety base, control, and mo-bile transmitters in the 769–775 MHz and 799–805 MHz frequency bands must be operated only in accordance with the rules in this section, to reduce the potential for interference to public re-ception of the signals of existing TV and DTV broadcast stations transmit-ting on TV Channels 62, 63, 64, 65, 67, 68 or 69.

(a) D/U ratios. Licensees of public safety stations must choose site loca-tions that are a sufficient distance from co-channel and adjacent channel TV and DTV stations, and/or must use reduced transmitting power or trans-mitting antenna height such that the following minimum desired signal to undesired signal ratios (D/U ratios) are met:

(1) The minimum D/U ratio for co- channel stations is 40 dB at the hypo-thetical Grade B contour (64 dBµV/m) (88.5 kilometers or 55.0 miles) of the TV station or 17 dB at the equivalent Grade B contour (41 dBµV/m) (88.5 kilo-meters or 55.0 miles) of the DTV sta-tion.

(2) The minimum D/U ratio for adja-cent channel stations is 0 dB at the hy-pothetical Grade B contour (64 dBµV/m) (88.5 kilometers or 55.0 miles) of the TV

station or ¥23 dB at the equivalent Grade B contour (41 dBµV/m) (88.5 kilo-meters or 55.0 miles) of the DTV sta-tion.

(b) Maximum ERP and HAAT. The maximum effective radiated power (ERP) and the antenna height above average terrain (HAAT) of the proposed land mobile base station, the associ-ated control station, and the mobile transmitters shall be determined using the methods described in this section.

(1) Each base station is limited to a maximum ERP of 1000 watts.

(2) Each control station is limited to a maximum ERP of 200 watts and a maximum HAAT of 61 m. (200 ft).

(3) Each mobile station is limited to a maximum ERP of 30 watts and a maximum antenna height of 6.1 m. (20 ft.).

(4) Each portable (handheld) trans-mitter is limited to a maximum ERP of 3 watts.

(5) All transmitters are subject to the power reductions given in Figure B of § 90.309 of this chapter, for antenna heights higher than 152 meters (500 ft).

(c) Methods. The methods used to cal-culate TV contours and antenna heights above average terrain are given in §§ 73.683 and 73.684 of this chapter. Tables to determine the necessary min-imum distance from the public safety station to the TV/DTV station, assum-ing that the TV/DTV station has a hy-pothetical or equivalent Grade B con-tour of 88.5 kilometers (55.0 miles), are located in § 90.309 and labeled as Tables B, D, and E. Values between those given in the tables may be determined by linear interpolation. The locations of existing and proposed TV/DTV sta-tions during the transition period are given in part 73 of this chapter and in the final proceedings of MM Docket No. 87–268.

The transition period is scheduled to end on December 31, 2006. After that time, unless otherwise directed by the Commission, public safety stations will no longer be required to protect recep-tion of co-channel or adjacent channel TV/DTV stations.

(1) Licensees of stations operating within the ERP and HAAT limits of paragraph (b) must select one of three methods to meet the TV/DTV protec-tion requirements, subject to Commis-sion approval:

(i) utilize the geographic separation specified in the tables referenced below;

(ii) Submit an engineering study jus-tifying the proposed separations based on the parameters of the land mobile station and the parameters, including authorized and/or applied for facilities, of the TV/DTV station(s) it is trying to protect; or,

(iii) obtain written concurrence from the applicable TV/DTV station(s). If this method is chosen, a copy of the agreement must be submitted with the application.

(2) The following is the method for geographic separations.

(i) Base stations having an antenna height (HAAT) less than 152 m. (500 ft.) shall afford protection to co-channel and adjacent channel TV/DTV stations in accordance with the values specified in Table B (co-channel frequencies based on 40 dB protection) and Table E (adjacent channel frequencies based on 0 dB protection) in § 90.309 of this part. For base stations having an antenna height (HAAT) between 152–914 meters (500–3,000 ft.) the effective radiated power must be reduced below 1 kilo-watt in accordance with the values shown in the power reduction graph in Figure B in § 90.309 of this part. For heights of more than 152 m. (500 ft.) above average terrain, the distance to the radio path horizon will be cal-culated assuming smooth earth. If the distance so determined equals or ex-ceeds the distance to the hypothetical or equivalent Grade B contour of a co- channel TV/DTV station (i.e., it ex-

ceeds the distance from the appropriate Table in § 90.309 to the relevant TV/ DTV station) an authorization will not be granted unless it can be shown in an engineering study (method 2) that ac-tual terrain considerations are such as to provide the desired protection at the actual Grade B contour (64 dBµV/m for TV and 41 dBµV/m for DTV stations), or that the effective radiated power will be further reduced so that, assuming free space attenuation, the desired pro-tection at the actual Grade B contour (64 dBµV/m for TV and 41 dBµV/m cov-erage contour for DTV stations) will be achieved. Directions for calculating powers, heights, and reduction curves are listed in § 90.309 for land mobile sta-tions. Directions for calculating cov-erage contours are listed in §§ 73.683–685 for TV stations and in § 73.625 for DTV stations.

(ii) Control and mobile stations (in-cluding portables) are limited in height and power and therefore shall afford protection to co-channel and adjacent channel TV/DTV stations in accord-ance with the values specified in Table D (co-channel frequencies based on 40 dB protection) in § 90.309 of this part and a minimum distance of 8 kilo-meters (5 miles) from all adjacent channel TV/DTV station hypothetical or equivalent Grade B contours (adja-cent channel frequencies based on 0 dB protection for TV stations and—23 dB for DTV stations). Since control and mobile stations may affect different TV/DTV stations than the associated base station, particular care must be taken by applicants to ensure that all the appropriate TV/DTV stations are considered (e.g., a base station may be operating on TV Channel 64 and the mobiles on TV Channel 69, in which case TV Channels 63, 64, 65, 68, and 69 must be protected). Since mobiles and portables are able to move and commu-nicate with each other, licensees or co-ordinators must determine the areas where the mobiles can and cannot roam in order to protect the TV/DTV

stations, and advise the mobile opera-tors of these areas and their restric-tions.

(iii) In order to protect certain TV/ DTV stations and to ensure protection from these stations which may have extremely large contours due to un-usual height situations, an additional distance factor must be used by all public safety base, control and mobile stations. For all co-channel and adja-cent channel TV/DTV stations which have an HAAT between 350 and 600 me-ters, public safety stations must add the following DISTANCE FACTOR to the value obtained from the referenced Tables in § 90.309 and to the distance for control and mobile stations on adja-cent TV/DTV channels (96.5 km).

DISTANCE FACTOR = (TV/DTV HAAT¥350) ÷ 14 in kilometers, where HAAT is the TV or DTV station antenna height above average terrain obtained from its au-thorized or proposed facilities, whichever is greater.

(iv) For all co-channel and adjacent channel TV/DTV stations which have an antenna height above average ter-rain greater than 600 meters, public safety stations must add 18 kilometers as the DISTANCE FACTOR to the value obtained from the referenced Ta-bles in § 90.309 and to the distance for control and mobile stations on adja-cent TV/DTV channels (96.5 km).

NOTE TO § 90.545: The 88.5 km (55.0 mi) Grade B service contour (64 dBµV/m) is based on a hypothetical TV station operating at an effective radiated power of one megawatt, a transmitting antenna height above average terrain of 610 meters (2000 feet) and the Com-mission’s R–6602 F(50,50) curves. See § 73.699 of this chapter. Maximum facilities for TV sta-tions operating in the UHF band are 5 megawatts effective radiated power at an an-tenna HAAT of 610 meters (2,000 feet). See § 73.614 of this chapter. The equivalent con-tour for DTV stations is based on a 41 dBµV/ m signal strength and the distance to the F(50,90) curve. See § 73.625 of this chapter.

§ 90.555 Information exchange. (a) Prior notification. Public safety li-

censees authorized to operate in the 763–775 MHz and 793–805 MHz bands may notify any licensee authorized to oper-ate in the 746–757, 758–763, 776–787, or 788–793 MHz bands that they wish to re-ceive prior notification of the activa-tion or modification of the licensee’s base or fixed stations in their area. Thereafter, the 746–757, 758–763, 776–787, or 788–793 MHz band licensee must pro-vide the following information to the public safety licensee at least 10 busi-ness days before a new base or fixed station is activated or an existing base or fixed station is modified:

(1) Location; (2) Effective radiated power; (3) Antenna height; and (4) Channels available for use. (b) Purpose of prior notification. The

prior coordination of base or fixed sta-tions is for informational purposes only. Public safety licensees are not af-forded the right to accept or reject the activation of a proposed base or fixed station or to unilaterally require changes in its operating parameters. The principal purposes of notification are to:

(1) Allow a public safety licensee to advise the 746–757, 758–763, 776–787, or 788–793 MHz band licensee whether it believes a proposed base or fixed sta-tion will generate unacceptable inter-ference;

(2) Permit 746–757, 758–763, 776–787, and 788–793 MHz band licensees to make voluntary changes in base or fixed sta-tion parameters when a public safety licensee alerts them to possible inter-ference; and,

(3) Rapidly identify the source if in-terference is encountered when the base or fixed station is activated.

(c) Public Safety Information Exchange. (1) Upon request by a 746–757, 758–763, 776–787, or 788–793 MHz band licensee, public safety licensees authorized to operate radio systems in the 763–775 and 793–805 MHz bands shall provide the operating parameters of their radio system to the 746–757, 758–763, 776–787, or 788–793 MHz band licensee.

(2) Public safety licensees who per-form the information exchange de-scribed in this section must notify the appropriate 746–757, 758–763, 776–787, or

788–793 MHz band licensees prior to any technical changes to their radio sys-tem.

§ 90.621 Selection and assignment of frequencies.

(a) Applicants for frequencies in the Public Safety and Business/Industrial/ Land Transportation Categories must specify on the application the fre-quencies on which the proposed system will operate pursuant to a rec-ommendation by the applicable fre-quency coordinator. Applicants for fre-quencies in the SMR Category must re-quest specific frequencies by including in their applications the frequencies requested.

(1) For trunked systems, the assign-ment of frequencies will be made in ac-cordance with applicable loading cri-teria and in accordance with the fol-lowing:

(i) Channels will be chosen and as-signed in accordance with §§ 90.615, 90.617, or 90.619.

(ii) A mobile station is authorized to transmit on any frequency assigned to its associated base station.

(iii) There are no limitations on the number of frequencies that may be trunked. Authorizations for non-SMR stations may be granted for up to 20 trunked frequency pairs at a time in accordance with the frequencies listed in §§ 90.615, 90.617, and 90.619.

(2) For conventional systems the as-signment of frequencies will be made in accordance with applicable loading cri-teria. Accordingly, depending upon the number of mobile units to be served, an applicant may either be required to share a channel, or, if an applicant shows a sufficient number of mobile units to warrant the assignment of one or more channels for its exclusive use, it may be licensed to use such channel or channels on an unshared basis in the area of operation specified in its appli-cation.

(i) Channels will be chosen and as-signed in accordance with §§ 90.615, 90.617, or 90.619.

(ii) A mobile station is authorized to transmit on any frequency assigned to its associated base station.

(b) Stations authorized on fre-quencies listed in this subpart, except for those stations authorized pursuant to paragraph (g) of this section and EA- based and MTA-based SMR systems, will be assigned frequencies solely on the basis of fixed distance separation criteria. The separation between co- channel systems will be a minimum of 113 km (70 mi) with one exception. For incumbent licensees in Channel Blocks F1 through V, that have received the consent of all affected parties or a cer-tified frequency coordinator to utilize an 18 dBµV/m signal strength inter-ference contour (see § 90.693), the sepa-ration between co-channel systems will be a minimum of 173 km (107 mi). The following exceptions to these separa-tions shall apply:

(1) Except as indicated in paragraph (b)(4) of this section, no station in Channel Blocks A through V shall be less than 169 km (105 mi) distant from a co-channel station that has been granted channel exclusivity and au-thorized 1 kW ERP on any of the fol-lowing mountaintop sites: Santiago Peak, Sierra Peak, Mount Lukens, Mount Wilson (California). Except as indicated in paragraph (b)(4) of this section, no incumbent licensee in Channel Blocks F1 through V that has received the consent of all affected par-ties or a certified frequency coordi-nator to utilize an 18 dBµV/m signal strength interference contour shall be less than 229 km (142 mi) distant from a co-channel station that has been granted channel exclusivity and au-thorized 1 kW ERP on any of the fol-lowing mountaintop sites: Santiago Peak, Sierra Peak, Mount Lukens, Mount Wilson (California).

(2) The separation between co-chan-nel stations that have been granted ex-clusivity and that are located at high sites in California north of 35° N Lati-tude and west of 118° W Longitude shall be determined as follows:

(i) Required co-channel separations between common antenna sites are given by table 1. A channel group as-signed to a station on a site listed in the vertical column may not be re-as-signed to a station on a site listed in

(4) Upon an applicant’s specific re-quest to the Commission or a fre-quency coordinator, co-channel sta-tions may be separated by less than 113 km (70 mi) by meeting certain trans-mitter ERP and antenna height cri-teria. The following table indicates separations assignable to such co-chan-nel stations for various transmitter power and antenna height combina-tions. The minimum separation per-mitted is 88 km (55 mi). Applicants will provide the Commission with a state-ment that the application is submitted for consideration under the table, a list

of all co-channel stations within 113 km (70 mi), and the DHAATs and ERPs for these stations and the applicant’s proposed station. Applicants seeking to be licensed for stations located at dis-tances less than those prescribed in the table are required to secure a waiver and must submit with the application, in addition to the above, an inter-ference analysis, based upon any of the generally-accepted terrain-based prop-agation models, that shows that co- channel stations would receive the same or greater interference protection than provided in the table. Requests for separations less than 88 km (55 mi) must also include an analysis of inter-ference potential from mobile trans-mitters to existing co-channel base sta-tion receivers. Applicants seeking a waiver must submit with their applica-tion a certificate of service indicating that concurrent with the submission of the application to the Commission or a coordinator, all co-channel licensees within the applicable area were served with a copy of the application and all attachments thereto. Licensees thus served may file an opposition to the ap-plication within 30 days from the date the application is filed with the Com-mission.

(i) The directional height of the an-tenna above average terrain (DHAAT) is calculated from the average of the antenna heights above average terrain from 3 to 16 km (2 to 10 mi) from the proposed site along a radial extending in the direction of the existing station and the radials 15 degrees to either side of that radial.

(ii) Except for the sites listed in para-graphs (b)(1), (b)(2), and (b)(3) of this section, additional co-channel distance separation must be afforded to an ex-isting station from an applicant wish-ing to locate a station less than 113 km (70 mi) from a co-channel station, where either the applicant’s or the ex-isting station is located at sites with DHAATs of 458 m (1500 ft) and above. The separation between short-spaced co-channel stations shall be deter-mined as follows:

(A) Calculate the DHAAT in each di-rection between every existing co- channel station with 113 km (70 mi) and the proposed station.

(B) In the table, locate the approxi-mate ERP and DHAAT values for the proposed and existing stations.

(C) When DHAAT values are greater than 458 m (1500 ft), use the required separation for 305 m (1000 ft) and add 1.6 km (1 mi) for every 30.5 km (100 ft), or increment thereof, of DHAAT above 458 m (1500 ft) to the distance indicated in the table. If both the proposed existing stations have DHAATs of 458 m (1500 ft) or more, the additional distance is sep-arately determined for each station and the combined distance is added to the distance obtained from the table. Protection to existing stations will be afforded only up to 113 km (70 mi).

1 Separations for stations on Santiago Peak, Sierra Peak, Mount Lukens, and Mount Wilson (CA) and the locations in the State of Washington listed in paragraph (b)(3) of this sec-tion are 56 km (35 mi) greater than those listed in the table above. In the event of conflict between this table and the table of additional California high elevation sites shown in para-graph (b)(2) of this section, the latter will apply.

2 Distances shown are derived from the R–6602 curves and are based upon a non-overlap of the 22 dBu (F50,10) inter-ference contour of the proposed station with the 40 dBu (F50,50) contour of the existing station(s). No consideration is given to the 40 dBu service contour of the proposed station and the 22 dBu contour of the existing station(s). The min-imum separation of stations will be 88 km (55 mi).

3 All existing stations are assumed to operate with 1000 watts ERP. When the ERP and/or DHAAT of a proposed sta-tion or the DHAAT of an existing station is not indicated in the table, the next higher value(s) must be used.

(5) The separation between co-chan-nel systems may be less than the sepa-rations defined above if an applicant submits with its application letters of concurrence indicating that the appli-cant and each co-channel licensee within the specified separation agree to accept any interference resulting from the reduced separation between their systems. Each letter from a co-channel licensee must certify that the system of the concurring licensee is con-structed and fully operational. The ap-plicant must also submit with its ap-plication a certificate of service indi-cating that all concurring co-channel licensees have been served with an ac-tual copy of the application.

(6) A station located closer than the distances provided in this section to a co-channel station that was authorized as short-spaced under paragraph (b)(4) of this section shall be permitted to modify its facilities as long as the sta-tion does not extend its 22 dBu contour beyond its maximum 22 dBu contour (i.e., the 22 dBu contour calculated using the station’s maximum power and antenna height at its original loca-tion) in the direction of the short- spaced station.

(7) Offset frequencies in the 811–821/ 856–866 MHz band for use only within U.S./Mexico border area, as designated in § 90.619(a), shall be considered co- channel with non-offset frequencies in this band as designated in § 90.613. New applications for frequencies in this band for stations adjacent to the U.S./ Mexico border area must comply with the co-channel separation provisions of this section.

(c) Conventional systems authorized on frequencies in the Public Safety (ex-cept for those systems that have par-ticipated in a formal regional planning process as described in § 90.16) and Busi-ness/Industrial/Land Transportation categories which have not met the

loading levels necessary for channel ex-clusivity will not be afforded co-chan-nel protection.

(d) UHF television translator sta-tions using UHF output channels from Channels 70 through 83 operate on a secondary basis to land mobile stations using the UHF bands allocated under this subpart for land mobile use. Ac-cordingly, such television translator stations will not be protected from in-terference from such authorized land mobile stations.

(e) Frequencies in the 809–817/854–862 MHz bands listed as available for eligi-bles in the Public Safety and Business/ Industrial/Land Transportation Cat-egories are available for inter-category sharing under the following conditions:

(1) Channels in the Public Safety and Business/Industrial/Land Transpor-tation categories will be available to eligible applicants in those categories only if there are no frequencies in their own category and no public safety sys-tems are authorized on those channels under consideration to be shared.

(2) Notwithstanding paragraph (e)(5) of this section, licensees of channels in the Business/Industrial/Land Transpor-tation category may request a modi-fication of the license, see § 1.947 of this chapter, to authorize use of the chan-nels for commercial operation. The li-censee may also, at the same time or thereafter, seek authorization to trans-fer or assign the license, see § 1.948 of this chapter, to any person eligible for licensing in the General or SMR cat-egories. Applications submitted pursu-ant to this paragraph must be filed in accordance with the rules governing other applications for commercial channels, and will be processed in ac-cordance with those rules. Grant of re-quests submitted pursuant to this paragraph is subject to the following conditions:

(i) A licensee that modifies its li-cense to authorize commercial oper-ations will not be authorized to obtain additional 800 MHz Business/Industrial/ Land Transportation category chan-nels for sites located within 113 km (70 mi.) of the station for which the license was modified, for a period of one year from the date the license is modified. This provision applies to the licensee, its controlling interests and their af-

filiates, as defined in § 1.2110 of this chapter.

(ii) With respect to licenses the ini-tial application for which was filed on or after November 9, 2000, requests sub-mitted pursuant to paragraph (e)(2) of this section may not be filed until five years after the date of the initial li-cense grant. In the case of a license that is modified on or after November 9, 2000 to add 800 MHz Business/Indus-trial/Land Transportation frequencies or to add or relocate base stations that expand the licensee’s interference con-tour, requests submitted pursuant to paragraph (e)(2) of this section for these frequencies or base stations may not be filed until five years after such modification.

(iii) Requests submitted pursuant to paragraph (e)(2) of this section must in-clude a certification that written no-tice of the modification application has been provided to all Public Safety li-censees, see § 90.20(a), with base sta-tions within 113 km (70 mi.) of the site of the channel(s) for which authoriza-tion for commercial use is sought that operate within 25 kHz of the center of those channel(s). If, pursuant to para-graph (e)(2) of this section, modifica-tion and assignment or transfer appli-cations are filed at different times, the written notice required by this para-graph must be provided each time.

(iv) The applicant must certify that it will take reasonable precautions to avoid causing harmful interference to Public Safety licensees, see § 90.20(a), and to take such action as may be nec-essary to eliminate interference to such licensees caused by its operations. (When an assignment or transfer appli-cation is filed pursuant to paragraph (e)(2) of this section, this representa-tion is required only of the assignee or transferee.) Licensees of stations suf-fering or causing harmful interference are expected to cooperate and resolve this problem by mutually satisfactory arrangements. If the licensees are un-able to do so, the Commission may im-pose restrictions including specifying the transmitter power, antenna height, or area or hours of operation.

(3) Licensees granted authorizations pursuant to paragraph (e)(2) of this sec-tion may at any time request modifica-tion of the license to authorize use of

the channels consistent with the rules governing the category to which they are allocated, provided that the li-censee meets the applicable eligibility requirements.

(4) [Reserved] (5) The frequency coordinator must

certify that frequencies are not avail-able in the applicant’s own category, and coordination is required from the applicable out-of-category coordinator.

(6) The out-of-category licensee must operate by the rules applicable to the category to which the frequency is al-located.

(f) Licensees of channels in the Busi-ness/Industrial/Land Transportation Categories in the 896–901/935–940 MHz bands may request a modification of the license, see § 1.947 of this chapter, to authorize use of the channels for com-mercial operation. The licensee may also, at the same time, or thereafter, seek authorization to transfer or as-sign the license, see § 1.948 of this chap-ter, to any person eligible for licensing in the General or SMR categories. Ap-plications submitted pursuant to this paragraph must be filed in accordance with the rules governing other applica-tions for commercial channels, and will be processed in accordance with those rules.

(g) Applications for Public Safety systems (both trunked and conven-tional) in the 806–809/851–854 MHz bands will be assigned and protected based on the criteria established in the appro-priate regional plan. See § 90.16 and the Report and Order in General Docket 87– 112.

(h) Channel numbers 511–520, 551–560, 591–600, 631–640, and 671–680 are allo-cated for Basic Exchange Tele-communications Radio Service as de-scribed in § 22.757 of this chapter. The FCC has proposed to remove these channels from the rural radiotelephone service in WT Docket No. 03–103 (FCC 03–95) released April 28, 2003 (68 FR 4403 July 25, 2003) which is pending.

provide facilities for the use of a single person or entity eligible under subparts B or C of this part, the applicant may be assigned only the number of fre-quency pairs justified on the basis of the requirement of the proposed single user of the system.

(c) No non-SMR licensee will be au-thorized an additional frequency pair for a conventional system within 64 kilometers (40 miles) of an existing conventional system, except where:

(1) The additional frequency pair will be used to provide radio facilities to a single entity and the additional fre-quency pair is justified on the basis of the requirements of the proposed single user; or,

(2) The licensee’s existing frequency pair(s) is loaded to prescribed levels.

(d) No licensee will be authorized fre-quencies for a conventional system if that licensee is operating an unloaded trunked system or has an application pending for a trunked system to serve multiple subscribers within 64 km (40 miles) of the requested conventional system.

§ 90.625 Other criteria to be applied in assigning channels for use in con-ventional systems of communica-tion.

(a) Where an applicant certifies on its application that a channel will be load-ed to 70 mobile stations, that channel will be made available to that appli-cant for its exclusive use in the area in which it proposes to operate. If the showing made justifies the assignment of more than one channel to the appli-cant, additional frequencies will be au-thorized.

(b) Where an applicant proposes to furnish service to eligibles under sub-parts B or C of this part on a commer-cial basis using a conventional system of communication, the applicant will be considered on the same basis as that of an applicant for private or shared communication facilities.

(c) No person authorized to operate any radio facility under the provisions of this subpart shall have a right to protest proposals on grounds other

than violation of or inconsistency with the provisions of this subpart. All grants are made subject to this condi-tion and to the other conditions and standards set out in this subpart.

§ 90.629 Extended implementation pe-riod.

Applicants requesting frequencies for either trunked or conventional oper-ations may be authorized a period of up to five (5) years for constructing and placing a system in operation in ac-cordance with the following:

(a) The applicant must justify an ex-tended implementation period. The jus-tification must describe the proposed system, state the amount of time nec-essary to construct and place the sys-tem in operation, identify the number of base stations to be constructed and placed in operation during each year of the extended construction period, and show that:

(1) The proposed system will require longer than twelve (12) months to con-struct and place in operation because of its purpose, size, or complexity; or

47 CFR Ch. I (10–1–10 Edition) § 90.631

(2) The proposed system is to be part of a coordinated or integrated wide- area system which will require more than twelve (12) months to plan, ap-prove, fund, purchase, construct, and place in operation; or

(3) The applicant is required by law to follow a multi-year cycle for plan-ning, approval, funding, and purchasing the proposed system.

(b) Where an applicant is required by law to follow a multi-year cycle for planning, approval, funding and pur-chasing a proposed system, the appli-cant must indicate whether funding ap-proval has been obtained and if not, when such funding approval is ex-pected.

(c) Authorizations under this section are conditioned upon the licensee con-structing and placing its system in op-eration within the authorized imple-mentation period and in accordance with an approved implementation plan of up to five years. Licensees must no-tify the Commission annually, using FCC Form 601, that they are in compli-ance with their yearly station con-struction commitments, but may re-quest amendment to these commit-ments at the time they file their an-nual certification. If the Commission approves the requested amendments to a licensee’s implementation commit-ments, the licensee’s extended imple-mentation authority will remain in ef-fect. If, however, the Commission con-cludes, at this or any other time, that a licensee has failed to meet its com-mitments, the Commission will termi-nate authority for the extended imple-mentation period. When the Commis-sion terminates an extended implemen-tation authority, the affected licensee will be given six months from the date of termination to complete system construction. At the end of any licens-ee’s extended implementation period, authorizations for all stations not con-structed and placed in operation will be cancelled. Trunked systems granted an extended implementation period must comply with the channel loading re-quirements of section 90.631(b). Conven-tional channels not loaded to 70 mobile units may be subject to shared use by the addition of other licensees.

(d) [Reserved]

(e) As of March 18, 1996, Specialized Mobile Radio systems are not eligible for extended implementation periods under this section. Additionally, all 800 MHz SMR licensees that are operating under extended implementation au-thority as of March 18, 1996 must, by May 16, 1996, demonstrate that con-tinuing to allow them to have an ex-tended period of time to construct their facilities is warranted and fur-thers the public interest. If a licensee’s extended implementation authority showing is approved by the Bureau, such licensee will be afforded an ex-tended implementation of two years or the remainder of its current extended implementation period, whichever is shorter. Upon the termination of this period, the authorizations for those fa-cilities that remain unconstructed will terminate automatically. If a licensee with a current extended implementa-tion period fails to submit the showing mentioned above within the designated timeframe or submits an insufficient or incomplete showing, such licensee will have six months from the last day on which it could timely file such a showing or from the disapproval of its request to construct the remaining fa-cilities covered under its implementa-tion plan to construct any unconstructed facilities for which it is authorized. The authorizations for those facilities remaining unconstructed after this six-month pe-riod will terminate automatically.

(f) Pursuant to § 90.155(b), the provi-sions of this section shall apply to local government entities applying for any frequency in the Public Safety Pool.

§ 90.631 Trunked systems loading, con-struction and authorization re-quirements.

(a) Non-SMR trunked systems will be authorized on the basis of a loading cri-teria of one hundred (100) mobile sta-tions per channel. For purposes of de-termining compliance with trunked system loading requirements under

this subpart, the term ‘‘mobile sta-tion’’ includes vehicular and portable mobile units and control stations.

(b) Each applicant for a non-SMR trunked system must certify that a minimum of seventy (70) mobiles for each channel authorized will be placed into operation within five (5) years of the initial license grant.

(c) Except for SMR applicants and as provided in paragraph (d) of this sec-tion, an applicant seeking to expand a trunked system by requesting addi-tional channels from the Commission, or through intercategory sharing, or through an assignment, must have a loading level of seventy (70) mobiles per channel on the existing system that is the subject of the expansion re-quest.

(d) In rural areas, a licensee of a trunked system may request to in-crease its system capacity by five more channels than it has constructed with-out meeting the loading requirements specified in paragraphs (b) and (c) of this section. A rural area is defined for purposes of this section as being be-yond a 100-mile radius of the des-ignated centers of the following urban-ized areas: New York, NY; Los Angeles, CA; Chicago, IL; Philadelphia, PA: San Francisco, CA; Detroit, MI; Boston, MA; Houston, TX; Washington, DC; Dallas-Fort Worth, TX; Miami, FL; Cleveland, OH; St. Louis, MO; Atlanta, GA; Pittsburgh, PA; Baltimore, MD; Minneapolis-St. Paul, MN; Seattle, WA; San Diego, CA; and Tampa-St. Pe-tersburg, FL. The coordinates for the centers of these areas are those ref-erenced in § 90.635, except that the co-ordinates (referenced to North Amer-ican Datum 1983 (NAD83)) for Tampa- St. Petersburg are latitude 28°00′1.1″ N, longitude 82°26′59.3″ W.

(e) Except as provided in § 90.629, li-censees of trunked facilities must com-plete construction within one year.

(f) If a station is not placed in perma-nent operation, in accordance with the technical parameters of the station au-thorization, within one year, except as provided in § 90.629, its license cancels automatically. For purposes of this section, a base station is not consid-ered to be placed in operation unless at least two associated mobile stations, or one control station and one mobile sta-

tion, are also placed in operation. An SMR licensee with facilities that have discontinued operations for 90 contin-uous days is presumed to have perma-nently discontinued operations, unless the licensee notifies the Commission otherwise, using FCC Form 601, prior to the end of the 90 day period and pro-vides a date on which operation will re-sume, which date must not be in excess of 30 additional days.

(g) Wide area systems may be author-ized to persons eligible for licensing under subparts B or C of this part upon an appropriate showing of need. Re-mote or satellite stations of wide area systems in the Public Safety, Special Emergency, Telephone Maintenance, and Power Radio Services may be au-thorized on a primary basis if such sta-tions are the first to be authorized in their area of operation on the fre-quency or group of frequencies. Remote or satellite stations of wide area sys-tems in all other services will be au-thorized only on a secondary, non-in-terference basis to cochannel licensees. To determine system loading, the total number of mobile units and control stations operating in the wide-area sys-tem shall be counted with respect to the total number of base station fre-quencies assigned to the system.

(h) Regional, statewide, or ribbon configuration systems may be author-ized to persons eligible for licensing under subparts B or C of this part upon an appropriate showing of need. In a ribbon, regional or statewide system, a mobile station will be counted for channel loading purposes only for the base station facility in the geographic area in which it primarily operates. If this cannot be determined, it will be counted fractionally over the number of base station facilities with which it communicates regularly.

the basis of a minimum loading cri-teria of seventy (70) mobile stations for each channel authorized.

(b) A channel will not be assigned to additional licensees when it is loaded to 70 mobile stations. Where a licensee does not load a channel to 70 mobiles the channel will be available for as-signment to other licensees. All au-thorizations for conventional systems are issued subject to this potential channel sharing condition.

(c) Except as provided in § 90.629 of this part, licensees of conventional sys-tems must place their authorized sta-tions in operation not later than one year after the date of grant of the sys-tem license.

(d) If a station is not placed in oper-ation within one year, except as pro-vided in Section 90.629 of this part, the license cancels automatically. For pur-poses of this section, a base station is not considered to be in operation un-less at least one associated mobile sta-tion is also in operation.

(e) A non-SMR licensee may apply for additional frequency pairs if its au-thorized conventional channel(s) is loaded to seventy (70) mobiles. Applica-tions may be considered for additional channels in areas where spectrum is still available and not applied for, even if the already authorized channel(s) is not loaded to 70 mobile units, upon an appropriate demonstration of need.

(f) Wide area systems may be author-ized to persons eligible for licensing under subparts B or C of this part upon an appropriate showing of need. For loading purposes, if the total number of mobile stations justifies the total num-ber of authorized based frequencies in a given area, the system will be con-strued to be loaded.

(g) Regional, statewide, or ribbon configuration systems may be author-ized to persons eligible for licensing under subparts B or C of this part upon an appropriate showing of need. In a ribbon, regional or statewide system, a mobile station will be counted for channel loading purposes only for the base station facility in the geographic area in which it primarily operates. If this cannot be determined, it will be counted fractionally over the number

of base station facilities with which it communicates regularly.

(b) Control stations associated with one or more mobile relay stations will be authorized only on the assigned fre-quency of the associated mobile sta-tion. Use of a mobile service frequency by a control station of a mobile relay system is subject to the condition that harmful interference shall not be caused to stations of licensees author-ized to use the frequency for mobile service communications.

(c) Trunked and conventional sys-tems that have exclusive-use status in their respective geographic areas may conduct fixed ancillary signaling and data transmissions subject to the fol-lowing requirements:

(1) All operations must be on a sec-ondary, non-interference basis to the primary mobile operation of any other licensee.

(2) The output power at the remote site must not exceed 30 watts.

(3) Any fixed transmitters will not count toward meeting the mobile load-ing requirements nor be considered in whole or in part as a justification for authorizing additional frequencies in the licensee’s mobile system.

(4) Automatic means must be pro-vided to deactivate the remote trans-mitter in the event the carrier remains on for a period in excess of three min-utes.

(5) Operational fixed stations author-ized pursuant to the provisions of para-graphs (c) and (d) of this section are ex-empt from the requirements of §§ 90.425 and 90.429.

Conventional and trunked radio sys-tems may be used:

(a) Only for purposes expressly al-lowed under this part.

(b) Only persons who are eligible for facilities, either under this subpart or in the radio service included under sub-parts B or C of this part.

(c) Except for licensees classified as CMRS providers under part 20 of this chapter, only for the transmission of messages or signals permitted in the services is which the participants are eligible.

(d) For digital or analog trans-missions.

(e) An SMRS licensee or a licensee who has been authorized a channel(s) on an exclusive basis, may use the sys-tem for the transmission of any base/ mobile message, page or signal per-mitted in the service in which the par-ticipants are eligible.

(f) Where the channel(s) is assigned to an SMRS licensee or exclusively to a single licensee, or where all users of a system agree, more than a single emission may be utilized within the au-thorized bandwidth. In such cases, the frequency stability requirements of § 90.213 shall not apply, but out-of-band emission limits of § 90.209 shall be met.

(g) Up to five (5) contiguous 809–816/ 854–861 band channels as listed in §§ 90.615, 90.617, and 90.619 may be au-thorized after justification for systems requiring more than the normal single channel bandwidth. If necessary, li-censees may trade channels amongst themselves in order to obtain contig-uous frequencies. Notification of such proposed exchanges shall be made to the appropriate frequency coordi-nator(s) and to the Commission by fil-ing an application for license modifica-tion.

(h) Up to 10 contiguous 896–901/935–940 MHz band channels as listed in § 90.617 may be combined for systems requiring more than the normal single channel bandwidth. If necessary, licensees may trade channels amongst themselves in order to obtain contiguous frequencies.

(b) Trunked systems of communica-tion, except as noted in paragraph (c) of this section, shall be identified through the use of an automatic device which transmits the call sign of the base station facility at 30 minute inter-vals. Such station identification shall be made on the lowest frequency in the base station trunk group assigned the licensee. Should this frequency be in use at the time station identification is required, such identification may be made at the termination of the com-munication in progress on this fre-quency. Identification may be made by voice or International Morse Code. When the call sign is transmitted in International Morse Code, it must be at a rate of between 15 to 20 words per minute and by means of tone modula-tion of the transmitter, the tone fre-quency being between 800 and 1000 hertz.

(c) Stations operating in either the 806–824/851–869 MHz or 896–901/935–940 MHz bands that are licensed on an ex-clusive basis, and normally employ dig-ital signals for the transmission of data, text, control codes, or digitized voice may also be identified by digital transmission of the call sign. A li-censee that identifies its station in this manner must provide the Commission, upon its request, information sufficient to decode the digital transmission and ascertain the call sign transmitted.

(d) Notwithstanding the require-ments set forth in this paragraph, sys-tems operated by geographic area CMRS licensees are subject only to the

station identification requirements of § 90.425(e).

§ 90.656 Responsibilities of base sta-tion licensees of Specialized Mobile Radio systems.

(a) The licensees of base stations that provide Specialized Mobile Radio serv-ice on a commercial basis of the use of individuals, Federal government agen-cies, or persons eligible for licensing under either subparts B or C of this part will be responsible for exercising effective operational control over all mobile and control stations that com-municate with the base station. The base station licensee will be respon-sible for assuring that its system is op-erated in compliance with all applica-ble rules and regulations.

(b) Customers that operate mobile units on a particular Specialized Mo-bile Radio system will be licensed to that system. A customer that operates temporarily on more than one system will be deemed, when communicating with the other system, to be tempo-rarily licensed to the other system and for that temporary period, the licensee of the other system will assume the same licensee responsibility for the customer’s mobile station(s) as if the customer’s stations were licensed to that other system.

POLICIES GOVERNING THE LICENSING AND USE OF MTA-BASED SMR SYSTEMS IN THE 896–901/935–940 MHZ BAND

§ 90.661 MTA-based SMR service areas. MTA licenses for SMR spectrum

blocks in the 896–901/935–940 MHz band listed in table 4B of § 90.617(d) are avail-able in 51 Major Trading Areas (MTAs) as defined in § 90.7. Within these MTAs, licenses will be authorized in ten chan-nel blocks as specified in table 4B of § 90.617(d) through the competitive bid-ding procedures described in subpart U of this part.

[60 FR 21991, May 4, 1995]

§ 90.663 MTA-based SMR system oper-ations.

(a) MTA-based licensees authorized in the 896–901/935–940 MHz band pursu-ant to § 90.661 may construct and oper-ate base stations using any frequency identified in their spectrum block any-

where within their authorized MTA, provided that:

(1) The MTA licensee affords protec-tion, in accordance with § 90.621(b), to all sites for which applications were filed on or prior to August 9, 1994.

(2) The MTA licensee complies with any rules and international agreements that restrict use of frequencies identi-fied in their spectrum block, including the provisions of § 90.619 relating to U.S./Canadian and U.S./Mexican border areas.

(3) The MTA licensee limits its field strength at any location on the border of the MTA service area in accordance with § 90.671 and masks its emissions in accordance with § 90.669.

(b) In the event that the authoriza-tion for a previously authorized co- channel station within the MTA licens-ee’s authorized spectrum block is ter-minated or revoked, the MTA licens-ee’s co-channel obligations to such sta-tion will cease upon deletion of the fa-cility from the Commission’s licensing record. The MTA licensee then will be able to construct and operate base sta-tions using such frequency.

[60 FR 21991, May 4, 1995]

§ 90.665 Authorization, construction and implementation of MTA li-censes.

(a) MTA licenses in the 896–901/935–940 MHz band will be issued for a term not to exceed ten years.

(b) MTA licensees in the 896–901/935– 940 MHz band will be permitted five years to construct their stations. This five-year period will commence with the issuance of the MTA-wide author-ization and will apply to all of the li-censee’s stations within the MTA spec-trum block, including any stations that may have been subject to an ear-lier construction deadline arising from a pre-existing authorization.

(c) Each MTA licensee in the 896–901/ 935–940 MHz band must, three years from the date of license grant, con-struct and place into operation a suffi-cient number of base stations to pro-vide coverage to at least one-third of the population of the MTA; further, each MTA licensee must provide cov-erage to at least two-thirds of the pop-ulation of the MTA five years from the date of license grant.

MTA licensee must demonstrate, through a showing to the Commission five years from the date of license grant, that it is providing substantial service. An MTA licensee must, three years from license grant, either show that the 1⁄3 population coverage stand-ard has been satisfied, or provide writ-ten notification that it has elected to show substantial service to the MTA five years from license grant. In addi-tion, as part of the election to provide a substantial service showing, each MTA licensee must, three years from license grant, indicate how it expects to demonstrate substantial service at five years. The MTA licensee must meet the population coverage bench-marks regardless of the extent to which incumbent licensees are present within the MTA block.

(d) MTA licensees who fail to meet the coverage requirements imposed at either the third or fifth years of their license term, or to make a convincing showing of substantial service, will for-feit the portion of the MTA license that exceeds licensed facilities con-structed and operating on the date of the MTA license grant.

§ 90.667 Grandfathering provisions for incumbent licensees.

(a) These provisions apply to all 900 MHz SMR licensees who obtained li-censes or filed applications for sec-ondary sites on or before August 9, 1994 (‘‘incumbent licensees’’), as well as to all 900 MHz SMR licensees who ob-tained authorizations pursuant to § 90.173(k). An incumbent licensee’s service area shall be defined by its originally-licensed 40 dBu field strength contour. Incumbent licensees are permitted to add new or modify transmit sites in this existing service area without prior notification to the Commission so long as their original 40 dBu field strength contour is not ex-panded.

(b) Incumbent licensees operating at multiple sites may, after grant of MTA licenses has been completed, exchange multiple site licenses for a single li-cense, authorizing operations through-out the contiguous and overlapping 40

dBu field strength contours of the mul-tiple sites. Incumbents exercising this license exchange option must submit specific information for each of their external base sites after the close of the 900 MHz SMR auction.

(c) Applications in the 900 MHz SMR service for secondary sites filed after August 9, 1994 shall be authorized on a secondary, non-interference basis to MTA licensee operations. No secondary sites shall be granted on this basis in an MTA once the MTA licensee has been selected.

[60 FR 48918, Sept. 21, 1995]

§ 90.669 Emission limits. (a) On any frequency in an MTA li-

censee’s spectrum block that is adja-cent to a non-MTA frequency, the power of any emission shall be attenu-ated below the transmitter power (P) by at least 43 plus 10 log10(P) decibels or 80 decibels, whichever is the lesser attenuation.

NOTE: The measurements of emission power can be expressed in peak or average values, provided they are expressed in the same parameters as the transmitter power.

(b) When an emission outside of the authorized bandwidth causes harmful interference, the Commission may, at its discretion, require greater attenu-ation than specified in this section.

[60 FR 21992, May 4, 1995]

§ 90.671 Field strength limits. The predicted or measured field

strength at any location on the border of the MTA service area for MTA li-censees shall not exceed 40 dBuV/m un-less all bordering MTA licensees agree to a higher field strength. MTA licens-ees are also required to coordinate their frequency usage with so-channel adjacent MTA licensees and all other affected parties. To the extent that a single entity obtains licenses for adja-cent MTAs on the same channel block, it will not be required to coordinate its operations in this manner. In the event that this standard conflicts with the MTA licensee’s obligation to provide co-channel protection to incumbent li-censees under § 90.621(b), the require-ments of § 90.621(b) shall prevail.

PROCEDURES AND PROCESS— UNACCEPTABLE INTERFERENCE

§ 90.672 Unacceptable interference to non-cellular 800 MHz licensees from 800 MHz cellular systems or part 22 Cellular Radiotelephone systems, and within the 900 MHz Business/ Industrial Land Transportation Pool.

(a) Definition. Except as provided in 47 CFR 90.617(k), unacceptable inter-ference to non-cellular licensees in the 800 MHz band from 800 MHz cellular systems or part 22 of this chapter, Cel-lular Radiotelephone systems and within the 900 MHz Business/Industrial Land Transportation (B/ILT) Pool will be deemed to occur when the below conditions are met:

(1) A transceiver at a site at which interference is encountered:

(i) Is in good repair and operating condition, and is receiving:

(A) A median desired signal strength of ¥104 dBm or higher if operating in the 800 MHz band, or a median desired signal strength of –88 dBm if operating in the 900 MHz B/ILT Pool, as measured at the R.F. input of the receiver of a mobile unit; or

(B) A median desired signal strength of ¥101 dBm or higher if operating in the 800 MHz band, or a median desired signal strength of –85 dBm if operating in the 900 MHz B/ILT Pool, as measured at the R.F. input of the receiver of a portable i.e., hand-held unit; and either

(ii) Is a voice transceiver: (A) With manufacturer published per-

formance specifications for the re-ceiver section of the transceiver equal to, or exceeding, the minimum stand-ards set out in paragraph (b) of this section, and;

(B) Receiving an undesired signal or signals which cause the measured Car-rier to Noise plus Interference (C/(I+N)) ratio of the receiver section of said transceiver to be less than 20 dB if op-erating in the 800 MHz band, or less than 17 dB if operating in the 900 MHz B/ILT Pool, or;

(iii) Is a non-voice transceiver receiv-ing an undesired signal or signals which cause the measured bit error rate (BER) (or some comparable speci-fication) of the receiver section of said transceiver to be more than the value

reasonably designated by the manufac-turer.

(2) Provided, however, that if the re-ceiver section of the mobile or portable voice transceiver does not conform to the standards set out in paragraph (b) of this section, then that transceiver shall be deemed subject to unaccept-able interference only at sites where the median desired signal satisfies the applicable threshold measured signal power in paragraphs (a)(1)(i) of this sec-tion after an upward adjustment to ac-count for the difference in receiver sec-tion performance. The upward adjust-ment shall be equal to the increase in the desired signal required to restore the receiver section of the subject transceiver to the 20 dB C/(I+N) ratio of paragraph (a)(1)(ii)(B) of this section. The adjusted threshold levels shall then define the minimum measured signal power(s) in lieu of paragraphs (a)(1)(i) of this section at which the li-censee using such non-compliant trans-ceiver is entitled to interference pro-tection.

(b) Minimum Receiver Requirements. Voice transceivers capable of operating in the 806–824 MHz portion of the 800 MHz band, or in the 900 MHz Business/ Industrial Land Transportation Pool, shall have the following minimum per-formance specifications in order for the system in which such transceivers are used to claim entitlement to full pro-tection against unacceptable inter-ference. (See paragraph (a)(2) of this section.)

(1) Voice units intended for mobile use: 75 dB intermodulation rejection ratio; 75 dB adjacent channel rejection ratio; –116 dBm reference sensitivity.

(2) Voice units intended for portable use: 70 dB intermodulation rejection ratio; 70 dB adjacent channel rejection ratio; –116 dBm reference sensitivity.

(3) Voice units intended for mobile or portable use in the 900 MHz Business/ Industrial Land Transportation Pool: 60 dB intermodulation rejection ratio; 60 dB adjacent channel rejection ratio; –116 dBm reference sensitivity.

47 CFR Ch. I (10–1–10 Edition) § 90.673

§ 90.673 Obligation to abate unaccept-able interference.

(a) Strict Responsibility. Any licensee who, knowingly or unknowingly, di-rectly or indirectly, causes or contrib-utes to causing unacceptable inter-ference to a non-cellular licensee in the 800 MHz band, as defined in this chap-ter, shall be strictly accountable to abate the interference, with full co-operation and utmost diligence, in the shortest time practicable. Interfering licensees shall consider all feasible in-terference abatement measures, includ-ing, but not limited to, the remedies specified in the interference resolution procedures set forth in this chapter. This strict responsibility obligation ap-plies to all forms of interference, in-cluding out-of-band emissions and intermodulation.

(b) Joint and Several Responsibility. If two or more licensees knowingly or un-knowingly, directly or indirectly, cause or contribute to causing unac-ceptable interference to a non-cellular licensee in the 800 MHz band, as defined in this chapter, such licensees shall be jointly and severally responsible for abating interference, with full coopera-tion and utmost diligence, in the short-est practicable time. This joint and several responsibility rule requires interfering licensees to consider all feasible interference abatement meas-ures, including, but not limited to, the remedies specified in the interference resolution procedures set forth in this chapter. This joint and several respon-sibility rule applies to all forms of in-terference, including out-of-band emis-sions and intermodulation.

(1) This joint and several responsi-bility rule requires interfering licens-ees to consider all feasible interference abatement measures, including, but not limited to, the remedies specified in the interference resolution proce-dures set forth in § 90.674(c). This joint and several responsibility rule applies to all forms of interference, including out-of-band emissions and intermodu-lation.

(2) Any licensee that can show that its signal does not directly or indi-rectly, cause or contribute to causing unacceptable interference to a non-cel-lular licensee in the 800 MHz band, as defined in this chapter, shall not be

held responsible for resolving unac-ceptable interference. Notwith-standing, any licensee that receives an interference complaint from a public safety/CII licensee shall respond to such complaint consistent with the in-terference resolution procedures set forth in this chapter.

[69 FR 67849, Nov. 22, 2004]

§ 90.674 Interference resolution proce-dures before, during and after band reconfiguration.

(a) Initial Notification. Any non-cel-lular licensee operating in the 806–824/ 851–869 MHz band who reasonably be-lieves it is receiving unacceptable in-terference, as described in § 90.672, shall provide an initial notification of the interference incident. This initial noti-fication of an interference incident shall be sent to all part 22 of this chap-ter Cellular Radiotelephone licensees and ESMR licensees who operate cel-lular base stations (‘‘cell sites’’) within 1,524 meters (5,000 feet) of the inter-ference incident.

(1) The initial notification of inter-ference shall include the following in-formation on interference:

(i) The specific geographical location where the interference occurs, and the time or times at which the interference occurred or is occurring;

(ii) A description of its scope and se-verity, including its source, if known;

(iii) The relevant Commission licens-ing information of the party suffering the interference; and

(iv) A single point of contact for the party suffering the interference.

(2) ESMR licensees, in conjunction with part 22 Cellular Radiotelephone li-censees, shall establish an electronic means of receiving the initial notifica-tion described in paragraph (a)(1) of this section. The electronic system must be designed so that all appro-priate 800 MHz ESMR and part 22 Cel-lular Radiotelephone licensees can be contacted about the interference inci-dent with a single notification. The electronic system for receipt of initial notification of interference complaints must be operating no later than Feb-ruary 22, 2005.

(3) ESMR licensees must respond to the initial notification described in paragraph (a)(1) of this section, as soon

as possible and no later than 24 hours of receipt of notification from a public safety/CII licensee. This response time may be extended to 48 hours after re-ceipt from other non-cellular licensees provided affected communications on these systems are not safety related.

(b) Interference analysis. ESMR licens-ees—who receive an initial notification described in paragraph (a) of this sec-tion—shall perform a timely analysis of the interference to identify the pos-sible source. Immediate on-site visits may be conducted when necessary to complete timely analysis. Interference analysis must be completed and correc-tive action initiated within 48 hours of the initial complaint from a public safety/CII licensee. This response time may be extended to 96 hours after the initial complaint from other non-cel-lular licensees provided affected com-munications on these systems are not safety related. Corrective action may be delayed if the affected licensee agrees in writing (which may be, but is not required to be, recorded via e-mail or other electronic means) to a longer period.

(c) Mitigation Steps. (1) All 800 MHz cellular system licensees and part 22 of this chapter Cellular Radiotelephone licensees who are responsible for caus-ing unacceptable interference shall take all affirmative measures to re-solve such interference. 800 MHz cel-lular system licensees found to con-tribute to harmful interference, as de-fined in § 90.672, shall resolve such in-terference in the shortest time prac-ticable. 800 MHz cellular system licens-ees and part 22 of this chapter Cellular Radiotelephone licensees must provide all necessary test apparatus and tech-nical personnel skilled in the operation of such equipment as may be necessary to determine the most appropriate means of timely eliminating the inter-ference. However, the means whereby interference is abated or the cell pa-rameters that may need to be adjusted is left to the discretion of involved 800 MHz cellular system licensees and/or part 22 of this chapter Cellular Radio-telephone licensees, whose affirmative measures may include, but not be lim-ited to, the following techniques:

(i) Increasing the desired power of the public safety signal;

(ii) Decreasing the power of the ESMR and/or part 22 Cellular Radio-telephone signal;

(iii) Modifying the ESMR and/or part 22 Cellular Radiotelephone systems an-tenna height;

(iv) Modifying the ESMR and/or part 22 Cellular Radiotelephone system an-tenna characteristics;

(v) Incorporating filters into ESMR and/or part 22 Cellular Radiotelephone system transmission equipment;

(vi) Permanently changing ESMR and/or part 22 Cellular Radiotelephone system frequencies; and

(vii) Supplying interference-resistant receivers to the affected public safety licensee(s). If this technique is used, in all circumstances, the ESMR and/or part 22 Cellular Radiotelephone licens-ees shall be responsible for all costs thereof.

(2) Whenever short-term interference abatement measures prove inadequate, the affected licensee shall, consistent with but not compromising safety, make all necessary concessions to ac-cepting interference until a longer- term remedy can be implemented.

(3) Discontinuing operations when clear and imminent danger exists. When a pub-lic safety licensee determines that a continuing presence of interference constitutes a clear and imminent dan-ger to life or property, the licensee causing the interference must dis-continue the associated operation im-mediately, until a remedy can be iden-tified and applied. The determination that a continuing presence exists that constitutes a clear and imminent dan-ger to life or property, must be made by written statement that:

(i) Is in the form of a declaration, no-tarized affidavit, or statement under penalty or perjury, from an officer or executive of the affected public safety licensee;

(ii) Thoroughly describes the basis of the claim of clear and imminent dan-ger;

(iii) Was formulated on the basis of either personal knowledge or belief after due diligence;

(iv) Is not proffered by a contractor or other third party; and

(v) Has been approved by the Chief of the Public Safety and Homeland Secu-rity Bureau or other designated Com-mission official. Prior to the author-ized official making a determination that a clear and imminent danger ex-ists, the associated written statement must be served by hand-delivery or receipted fax on the applicable offend-ing licensee, with a copy transmitted by the fastest available means to the Washington, DC office of the Commis-sion’s Public Safety and Homeland Se-curity Bureau.

§ 90.675 Information exchange. (a) Prior coordination. Public safety/

CII licensees may notify an ESMR or part 22 Cellular Radiotelephone li-censee that they wish to receive prior notification of the activation or modi-fication of ESMR or part 22 Cellular Radiotelephone cell sites in their area. Thereafter, the ESMR or part 22 Cel-lular Radiotelephone licensee must provide the following information to the public safety/CII licensee at least 10 business days before a new cell site is activated or an existing cell site is modified:

(1) Location; (2) Effective radiated power; (3) Antenna height; (4) Channels available for use. (b) Purpose of prior coordination. The

coordination of cell sites is for infor-mational purposes only: public safety/ CII licensees are not afforded the right to accept or reject the activation of a proposed cell or to unilaterally require changes in its operating parameters. The principal purposes of notification are to:

(1) Allow a public safety/CII licensee to advise the ESMR or part 22 Cellular Radiotelephone licensee whether it be-lieves a proposed cell will generate un-acceptable interference;

(2) Permit ESMR or part 22 Cellular Radiotelephone licensees to make vol-untary changes in cell parameters when a public safety licensee alerts them to possible interference; and

(3) Rapidly identify the source if in-terference is encountered when the cell is activated.

(c) Public safety information exchange. (1) Upon request by an ESMR or part 22 Cellular Radiotelephone licensee, pub-lic safety/CII licensees who operate radio systems in the 806–824/851–869 MHz shall provide the operating pa-rameters of their radio system to the ESMR or part 22 Cellular Radio-telephone licensee.

(2) Public safety licensees who per-form the information exchange as de-scribed in this section must notify the appropriate ESMR and part 22 Cellular Radiotelephone licensees prior to any technical changes to their radio sys-tem.

EFFECTIVE DATE NOTE: At 69 FR 67849, Nov. 22, 2004, § 90.675 was added. This section con-tains information collection and record-keeping requirements and will not become effective until approval has been given by the Office of Management and Budget.

§ 90.676 Transition administrator for reconfiguration of the 806–824/851– 869 MHz band in order to separate cellular systems from non-cellular systems.

The Transition Administrator will be an independent party with no financial interest in any 800 MHz licensee; and will be selected by a committee rep-resentative of 800 MHz licensees. The Transition Administrator will serve both a ministerial role and a function similar to a special master in a judicial proceeding.

(a) The duties of the Transition Ad-ministrator will include, but not be limited to:

(1) Obtaining estimates from licens-ees regarding the cost of reconfiguring their systems and ensuring that esti-mates contain a firm work schedule. The Transition Administrator will re-tain copies of all estimates and make them available to the Commission on request.

(2) Mediating disputes regarding cost estimates for reconfiguring a system.

(3) Issuing the Draw Certificate to authorize and instruct the Letter of Credit Trustee to draw down on the Letter of Credit to pay relocation costs in connection with reconfiguring a li-censee’s system.

(4) Establishing a relocation schedule on a NPSPAC region-by-region basis, prioritizing the regions on the basis of

population. However, should a given re-gion be encountering unusually severe amounts of unacceptable interference, that region may be moved up in pri-ority. Any party disputing such a change in priority may refer the mat-ter to the Chief, Public Safety and Homeland Security Bureau, who here-by is delegated the authority to resolve such disputes. The Transition Adminis-trator may direct that adjoining re-gions be reconfigured simultaneously when conditions so require.

(5) The Transition Administrator will coordinate relocation of a NPSPAC Re-gion’s NPSPAC channels with the rel-evant Regional Planning Committee(s) prior to commencing band reconfigura-tion in a NPSPAC Region.

(b) Once band reconfiguration com-mences in a given NPSPAC Region, the Transition Administrator will;

(1) Monitor the retuning schedule and resolve any schedule delays or refer same to the Chief, Public Safety and Homeland Security Bureau, for resolu-tion;

(2) Coordinate with adjoining NPSPAC Regions to ensure that inter-ference is not being caused to their ex-isting facilities from relocated sta-tions;

(3) Provide quarterly progress reports to the Commission in such detail as the Commission may require and include, with such reports, certifications by Nextel and the relevant licensees that relocation has been completed and that both parties agree on the amount re-ceived from the letter of credit pro-ceeds in connection with relocation of the licensees’ facilities. The report shall include description of any dis-putes that have arisen and the manner in which they were resolved. These quarterly reports need not be audited. The Transition Administrator may se-lect the dates for filing the quarterly progress reports;

(4) Provide the Chief, Public Safety and Homeland Security Bureau, with an annual audited statement of reloca-tion funds expended to date, including salaries and expenses of Transition Ad-ministrator. The Transition Adminis-trator may select the date for filing the annual audited statement;

(5) Facilitate resolution of disputes by mediation; or referral of the parties

to alternative dispute resolution serv-ices as described in § 90.677(d).

(6) Notify the Commission when band reconfiguration is complete in each 800 MHz NPSPAC Region and identify which vacant channels are exclusively available to eligible applicants in the Public Safety or Critical Infrastruc-ture Industry Categories as set forth in §sect; 90.615(a), (b) and 90.617(g), (h).

(c) The Transition Administrator may not serve as the repository of funds used in band reconfiguration, ex-cepting such sums as Nextel may pay for the Transition Administrator’s services. Moreover, the Transition Ad-ministrator will not be certified by the Commission as a frequency coordi-nator.

[69 FR 67849, Nov. 22, 2004, as amended at 70 FR 6760, Feb. 8, 2005; 70 FR 76711, Dec. 28, 2005; 71 FR 69038, Nov. 29, 2006]

§ 90.677 Reconfiguration of the 806– 824/851–869 MHz band in order to separate cellular systems from non- cellular systems.

In order to facilitate reconfiguration of the 806–824/851–869 MHz band (‘‘800 MHz band’’) to separate high-density cellular systems from non-cellular sys-tems, Nextel Communications, Inc. (Nextel) may relocate incumbents within the 800 MHz band by providing ‘‘comparable facilities.’’ For the lim-ited purpose of band reconfiguration, the provisions of § 90.157 shall not apply and inter-category sharing will be per-mitted under all circumstances. Such relocation is subject to the following provisions:

(a) Within thirty days of Commission approval of the Transition Adminis-trator, the Transition Administrator described in § 90.676 will provide the Commission with a schedule detailing when band reconfiguration shall com-mence for each NPSPAC Region. The plan should also detail—by NPSPAC Region—which relocation option each non-Nextel ESMR licensees has chosen. The Chief, Public Safety and Homeland Security Bureau will finalize and ap-prove such a plan. The schedule shall provide for completion of band recon-figuration in no more than thirty-six months following release of a public

notice announcing the start date of re-configuration in the first NPSPAC re-gion. Relocation will commence ac-cording to the schedule set by the Transition Administrator but all sys-tems must have commenced reconfig-uration within thirty months of release of a public notice announcing the start date of reconfiguration in the first NPSPAC region.

(b) Voluntary negotiations. Thirty days before the start date for each NPSPAC region other than Region 47, the Chief, Public Safety and Homeland Security Bureau will issue a public no-tice initiating a three-month voluntary negotiation period. During this vol-untary negotiation period, Nextel and all incumbents may negotiate any mu-tually agreeable relocation agreement. Sprint Nextel and relocating incum-bents may agree to conduct face-to- face negotiations or either party may elect to communicate with the other party through the Transition Adminis-trator.

(c) Mandatory negotiations. If no agreement is reached by the end of the voluntary period, a three-month man-datory negotiation period will begin during which both Sprint Nextel and the incumbents must negotiate in ‘‘good faith.’’ In Region 47, a 90-day mandatory negotiation period will begin 60 days after the effective date of the Third Report and Order and Third Further Notice of Proposed Rule-making in WT Docket 02–55. Sprint Nextel and relocating incumbents may agree to conduct face-to-face negotia-tions or either party may elect to com-municate with the other party through the Transition Administrator. All par-ties are charged with the obligation of utmost ‘‘good faith’’ in the negotiation process. Among the factors relevant to a ‘‘good-faith’’ determination are:

(1) Whether the party responsible for paying the cost of band reconfiguration has made a bona fide offer to relocate the incumbent to comparable facilities;

(2) The steps the parties have taken to determine the actual cost of reloca-tion to comparable facilities; and

(3) Whether either party has unrea-sonably withheld information, essen-tial to the accurate estimation of relo-cation costs and procedures, requested by the other party. The Transition Ad-

ministrator may schedule mandatory settlement negotiations and mediation sessions and the parties must conform to such schedules.

(d) Transition Administrator. (1) The Transition Administrator, or other me-diator, shall attempt to resolve dis-putes referred to it before the conclu-sion of the mandatory negotiation pe-riod as described in § 90.677(c) within thirty working days after the Transi-tion Administrator has received a sub-mission by one party and a response from the other party. Any party there-after may seek expedited non-binding arbitration which must be completed within thirty days of the Transition Administrator’s, or other mediator’s recommended decision or advice. Should issues still remain unresolved after mediation or arbitration they shall be referred to the Chief, Public Safety and Homeland Security Bureau within ten days of the Transition Ad-ministrator’s or other mediator’s ad-vice, or if arbitration has occurred, within ten days of the completion of arbitration. When referring an unre-solved matter to the Chief, Public Safety and Homeland Security Bureau, the Transition Administrator shall for-ward the entire record on any disputed issues, including such dispositions thereof that the Transition Adminis-trator has considered. Upon receipt of such record and advice, the Commis-sion will decide the disputed issues based on the record submitted. The au-thority to make such decisions is dele-gated to the Chief, Public Safety and Homeland Security Bureau who may decide the disputed issue or designate it for an evidentiary hearing before an Administrative Law Judge. If the Chief, Public Safety and Homeland Se-curity Bureau decides an issue, any party to the dispute wishing to appeal the decision may do so by filing with the Commission, within ten days of the effective date of the initial decision, a Petition for de novo review; whereupon the matter will be set for an evi-dentiary hearing before an Administra-tive Law Judge. Any disputes sub-mitted to the Transition Adminis-trator after the conclusion of the man-datory negotiation period as described in § 90.677(c) shall be resolved as de-scribed in § 90.677(d)(2).

(2) If no agreement is reached during either the voluntary or mandatory ne-gotiating periods, all disputed issues shall be referred to the Transition Ad-ministrator, or other mediator, who shall attempt to resolve them. If dis-puted issues remain thirty working days after the end of the mandatory negotiation period, the Transition Ad-ministrator shall forward the record to the Chief, Public Safety and Homeland Security Bureau, together with advice on how the matter(s) may be resolved. The Chief, Public Safety and Homeland Security Bureau is hereby delegated the authority to rule on disputed issues, de novo. If the Chief, Public Safety and Homeland Security Bureau decides an issue, any party to the dis-pute wishing to appeal the decision may do so by filing with the Commis-sion, within ten days of the effective date of the initial decision, a Petition for de novo review; whereupon the mat-ter will be set for an evidentiary hear-ing before an Administrative Law Judge.

(e) Waiver Requests. Incumbents who wish not to relocate according to the schedule may petition the Commission for a waiver of the relocation obliga-tion. Such a waiver would only be granted on a strict non-interference basis.

(f) Comparable Facilities. The replace-ment system provided to an incumbent must be at least equivalent to the ex-isting 800 MHz system with respect to the four factors described in § 90.699(d) part.

(g) Information Exchange. Absent agreement between parties, the Transi-tion Administrator will be responsible for determining the information that relocating incumbents must supply in support of a relocation agreement.

(h) The relevant Regional Planning Committee shall be informed of any proposed changes to any NPSPAC channel.

POLICIES GOVERNING THE LICENSING AND USE OF EA-BASED SMR SYSTEMS IN THE 809–824/851–869 MHZ BAND

§ 90.681 EA-based SMR service areas. EA licenses in for channels 711

through 830 and Spectrum Blocks A through V listed in Tables 4 and 5 of § 90.617 are available in 175 Economic Areas (EAs) as defined in § 90.7.

[69 FR 67852, Nov. 22, 2004]

§ 90.683 EA-based SMR system oper-ations.

(a) EA-based licensees authorized in the 809–824/854–869 MHz band pursuant to § 90.681 of this part may construct and operate base stations using any of the base station frequencies identified in their spectrum block anywhere within their authorized EA, provided that:

(1) The EA licensee affords protec-tion, in accordance with § 90.621(b), to all previously authorized co-channel stations that are not associated with another EA license;

(2) The EA licensee complies with any rules and international agreements that restrict use of frequencies identi-fied in their spectrum block, including the provisions of § 90.619 relating to U.S./Canadian and U.S./Mexican border areas;

(3) The EA licensee limits the field strength of its base stations at any lo-cation on the border of the EA service area in accordance with § 90.689;

(4) Upon request by an incumbent li-censee or the Commission, the EA li-censees shall furnish the technical pa-rameters, location and coordinates of the completion of the addition, re-moval, relocation or modification of any of its facilities within the EA. The EA licensee must provide such infor-mation within ten (10) days of receiv-ing a written request.

(5) For any construction or alter-ation that would exceed the require-ments of § 17.7 of this chapter, licensees must notify the appropriate Regional Office of the Federal Aviation Adminis-tration (FAA Form 7460–1) and file a re-quest for antenna height clearance and obstruction marking and lighting spec-ifications (FCC Forn 854) with the FCC, WTB, Support Services Branch, Gettys-burg, PA 17325.

(6) Any additional transmitters placed in operation must not have a significant environmental effect as de-fined by §§ 1.1301 through 1.1319 of this chapter.

(b) In the event that the authoriza-tion for a previously authorized co- channel station within the EA licens-ee’s spectrum block is terminated or revoked, the EA licensee’s co-channel obligations to such station will cease upon deletion of the facility from the Commission’s official licensing records, and the EA licensee then will be able to construct and operate without regard to that previous authorization.

[61 FR 6158, 6159, Feb. 16, 1996, as amended at 62 FR 41216, July 31, 1997; 63 FR 68970, Dec. 14, 1998; 69 FR 67852, Nov. 22, 2004]

§ 90.685 Authorization, construction and implementation of EA licenses.

(a) EA licenses in the 809–824/854–869 MHz band will be issued for a term not to exceed ten years. Additionally, EA licensees generally will be afforded a renewal expectancy only for those sta-tions put into service after August 10, 1996.

(b) EA licensees in the 809–824/854–869 MHz band must, within three years of the grant of their initial license, con-struct and place into operation a suffi-cient number of base stations to pro-vide coverage to at least one-third of the population of its EA-based service area. Further, each EA licensee must provide coverage to at least two-thirds of the population of the EA-based serv-ice area within five years of the grant of their initial license. EA-based li-censees may, in the alternative, pro-vide substantial service to their mar-kets within five years of the grant of their initial license. Substantial serv-ice shall be defined as: ‘‘Service which is sound, favorable, and substantially above a level of mediocre service.’’

(c) Channel use requirement. In addi-tion to the population coverage re-quirements described in this section, we will require EA licensees in Channel blocks A, B and C in the 816–821/861–866 MHz band to construct 50 percent of the total channels included in their spectrum block in at least one location in their respective EA-based service area within three years of initial li-cense grant and to retain such channel

usage for the remainder of the con-struction period.

(d) An EA licensee’s failure to meet the population coverage requirements of paragraphs (b) and (c) of this sec-tion, will result in forfeiture of the en-tire EA license. Forfeiture of the EA li-cense, however, would not result in the loss of any constructed facilities au-thorized to the licensee prior to the date of the commencement of the auc-tion for the EA licenses.

(e) EA licensees operating on chan-nels listed in § 90.614(b) and (c) must implement an Enhanced Specialized Mobile Radio (ESMR) system—as de-fined in § 90.7—on their EA license and any associated site-based licenses prior to the expiration date of the EA li-cense. EA licensees operating on these channels shall follow the construction notification procedures set forth in § 1.946(d) of this chapter. Failure to im-plement an ESMR system on their EA and site-based licenses before the expi-ration date of the EA license will re-sult in termination of the EA license and any associated site-based licenses pursuant to § 1.946(c) of this chapter.

[62 FR 41216, July 31, 1997, as amended at 69 FR 67852, Nov. 22, 2004; 70 FR 6760, Feb. 8, 2005; 70 FR 76712, Dec. 28, 2005]

§ 90.687 Special provisions regarding assignments and transfers of au-thorizations for incumbent SMR li-censees in the 809–824/854–869 MHz band.

An SMR license initially authorized on any of the channels listed in Tables 4 and 5 of § 90.617 may transfer or assign its channel(s) to another entity subject to the provisions of § 1.948 of this chap-ter and § 90.609(b). If the proposed transferee or assignee is the EA li-censee for the spectrum block to which the channel is allocated, such transfer or assignment presumptively will be deemed to be in the public interest. However, such presumption will be re-buttable.

§ 90.689 Field strength limits. (a) For purposes of implementing

§§ 90.689 through 90.699, predicted 36 and 40 dBµV/m contours shall be calculated using Figure 10 of § 73.699 of this chap-ter with a correction factor of ¥9 dB,

and predicted 18 and 22 dBµV/m con-tours shall be calculated using Figure 10a of § 73.699 of this chapter with a cor-rection factor of ¥9 dB.

(b) The predicted or measured field strength at any location on the border of the EA-based service area for EA li-censees must not exceed 40 dBuV/m un-less all bordering EA licensees agree to a higher field strength. In the event that this standard conflicts with the EA licensee’s obligation to provide co- channel protection to incumbent li-censees pursuant to § 90.621(b), the re-quirements of § 90.621(b) shall prevail.

[61 FR 6158, 6159, Feb. 16, 1996, as amended at 62 FR 41216, July 31, 1997]

§ 90.691 Emission mask requirements for EA-based systems.

(a) Out-of-band emission requirement shall apply only to the ‘‘outer’’ chan-nels included in an EA license and to spectrum adjacent to interior channels used by incumbent licensees. The emis-sion limits are as follows:

(1) For any frequency removed from the EA licensee’s frequency block by up to and including 37.5 kHz, the power of any emission shall be attenuated below the transmitter power (P) in watts by at least 116 Log10(f/6.1) deci-bels or 50 + 10 Log10(P) decibels or 80 decibels, whichever is the lesser at-tenuation, where f is the frequency re-moved from the center of the outer channel in the block in kilohertz and where f is greater than 12.5 kHz.

(2) For any frequency removed from the EA licensee’s frequency block greater than 37.5 kHz, the power of any emission shall be attenuated below the transmitter power (P) in watts by at least 43 + 10Log10(P) decibels or 80 deci-bels, whichever is the lesser attenu-ation, where f is the frequency removed from the center of the outer channel in the block in kilohertz and where f is greater than 37.5 kHz.

(b) When an emission outside of the authorized bandwidth causes harmful interference, the Commission may, at its discretion, require greater attenu-ation than specified in this section.

§ 90.693 Grandfathering provisions for incumbent licensees.

(a) General provisions. These provi-sions apply to ‘‘incumbent licensees,’’

all 800 MHz licensees authorized in the 809–821/854–866 MHz band who obtained licenses or filed applications on or be-fore December 15, 1995.

(b) Spectrum blocks A through V. An incumbent licensee’s service area shall be defined by its originally licensed 40 dBµV/m field strength contour and its interference contour shall be defined as its originally-licensed 22 dBµV/m field strength contour. The ‘‘originally-li-censed’’ contour shall be calculated using the maximum ERP and the ac-tual height of the antenna above aver-age terrain (HAAT) along each radial. Incumbent licensees are permitted to add, remove or modify transmitter sites within their original 22 dBµV/m field strength contour without prior notification to the Commission so long as their original 22 dBµV/m field strength contour is not expanded. In-cumbent licensee protection extends only to its 40 dBµV/m signal strength contour. Pursuant to the minor modi-fication notification procedures set forth in 1.947(b), the incumbent li-censee must notify the Commission within 30 days of any change in tech-nical parameters for stations that are authorized under a waiver of 90.621(b)(4), or that are authorized under 90.621(b)(5).

(c) Special provisions for spectrum blocks F1 through V. Incumbent licens-ees that have received the consent of all affected parties or a certified fre-quency coordinator to utilize an 18 dBµV/m signal strength interference contour shall have their service area defined by their originally-licensed 36 dBµV/m field strength contour and their interference contour shall be de-fined as their originally-licensed 18 dBµV/m field strength contour. The ‘‘originally-licensed’’ contour shall be calculated using the maximum ERP and the actual HAAT along each ra-dial. Incumbent licensees seeking to utilize an 18 dBµV/m signal strength in-terference contour shall first seek to obtain the consent of affected co-chan-nel incumbents. When the consent of a co-channel licensee is withheld, an in-cumbent licensee may submit to any certified frequency coordinator an en-gineering study showing that inter-ference will not occur, together with proof that the incumbent licensee has

sought consent. Incumbent licensees are permitted to add, remove or modify transmitter sites within their original 18 dBµV/m field strength contour with-out prior notification to the Commis-sion so long as their original 18 dBµV/ m field strength contour is not ex-panded. Incumbent licensee protection extends only to its 36 dBµV/m signal strength contour. Pursuant to the minor modification notification proce-dures set forth in 1.947(b), the incum-bent licensee must notify the Commis-sion within 30 days of any change in technical parameters for stations that are authorized under a waiver of 90.621(b)(4), or that are authorized under 90.621(b)(5).

(d) Consolidated license—(1) Spectrum blocks A through V. Incumbent licensees operating at multiple sites may, after grant of EA licenses has been com-pleted, exchange multiple site licenses for a single license, authorizing oper-ations throughout the contiguous and overlapping 40 dBµV/m field strength contours of the multiple sites. Incum-bents exercising this license exchange option must submit specific informa-tion on Form 601 for each of their ex-ternal base sites after the close of the 800 MHz SMR auction. The incumbent’s geographic license area is defined by the contiguous and overlapping 22 dBµV/m contours of its constructed and operational external base stations and interior sites that are constructed within the construction period applica-ble to the incumbent. Once the geo-graphic license is issued, facilities that are added within an incumbent’s exist-ing footprint and that are not subject to prior approval by the Commission will not be subject to construction re-quirements.

(2) Special Provisions for Spectrum Blocks F1 through V. Incumbent licens-ees that have received the consent of all affected parties or a certified fre-quency coordinator to utilize an 18 dBµV/m signal strength interference contour operating at multiple sites may, after grant of EA licenses has been completed, exchange multiple site licenses for a single license. This single site license will authorize operations throughout the contiguous and over-lapping 36 dBµV/m field strength con-tours of the multiple sites. Incumbents

exercising this license exchange option must submit specific information on Form 601 for each of their external base sites after the close of the 800 SMR auction. The incumbent’s geographic license area is defined by the contig-uous and overlapping 18 dBµV/m con-tours of its constructed and oper-ational external base stations and inte-rior sites that are constructed within the construction period applicable to the incumbent. Once the geographic li-cense is issued, facilities that are added within an incumbent’s existing footprint and that are not subject to prior approval by the Commission will not be subject to construction require-ments.

§ 90.699 Transition of the upper 200 channels in the 800 MHz band to EA licensing.

In order to facilitate provision of service throughout an EA, an EA li-censee may relocate incumbent licens-ees in its EA by providing ‘‘comparable facilities’’ on other frequencies in the 800 MHz band. Such relocation is sub-ject to the following provisions:

(a) EA licensees may negotiate with incumbent licensees as defined in § 90.693 operating on frequencies in Spectrum Blocks A, B, and C for the purpose of agreeing to terms under which the incumbents would relocate their operations to other frequencies in the 800 MHz band, or alternatively, would accept a sharing arrangement with the EA licensee that may result in an otherwise impermissible level of interference to the incumbent licens-ee’s operations. EA licensees may also negotiate agreements for relocation of the incumbents’ facilities within Spec-trum Blocks A, B or C in which all in-terested parties agree to the relocation of the incumbent’s facilities elsewhere within these bands. ‘‘All interested parties’’ includes the incumbent li-censee, the EA licensee requesting and paying for the relocation, and any EA licensee of the spectrum to which the incumbent’s facilities are to be relo-cated.

(b) The relocation mechanism con-sists of two phases that must be com-pleted before an EA licensee may pro-ceed to request the involuntary reloca-tion of an incumbent licensee.

(1) Voluntary negotiations. There is a one year voluntary period during which an EA licensee and an incumbent may negotiate any mutually agreeable relo-cation agreement. The Commission will announce the commencement of the first phase voluntary period by Public Notice. EA licensees must no-tify incumbents operating on fre-quencies included in their spectrum block of their intention to relocate such incumbents within 90 days of the release of the Public Notice that com-mences the voluntary negotiation pe-riod. Failure on the part of the EA li-censee to notify the incumbent li-censee during this 90 period of its in-tention to relocate the incumbent will result in the forfeiture of the EA li-censee’s right to request involuntary relocation of the incumbent at any time in the future.

(2) Mandatory negotiations. If no agreement is reached by the end of the voluntary period, a one-year manda-tory negotiation period will begin dur-ing which both the EA licensee and the incumbent must negotiate in ‘‘good faith.’’ Failure on the part of the EA li-censee to negotiate in good faith dur-ing this mandatory period will result in the forfeiture of the EA licensee’s right to request involuntary relocation of the incumbent at any time in the fu-ture.

(c) Involuntary relocation procedures. If no agreement is reached during ei-ther the voluntary or mandatory nego-tiating periods, the EA licensee may request involuntary relocation of the incumbent’s system. In such a situa-tion, the EA licensee must:

(1) Guarantee payment of relocation costs, including all engineering, equip-ment, site and FCC fees, as well as any legitimate and prudent transaction ex-penses incurred by the incumbent li-censee that are directly attributable to an involuntary relocation, subject to a cap of two percent of the hard costs in-volved. Hard costs are defined as the actual costs associated with providing a replacement system, such as equip-ment and engineering expenses. EA li-

censees are not required to pay incum-bent licensees for internal resources devoted to the relocation process. EA licensees are not required to pay for transaction costs incurred by incum-bent licensees during the voluntary or mandatory periods once the involun-tary period is initiated, or for fees that cannot be legitimately tied to the pro-vision of comparable facilities;

(2) Complete all activities necessary for implementing the replacement fa-cilities, including engineering and cost analysis of the relocation procedure and, if radio facilities are used, identi-fying and obtaining, on the incum-bents’ behalf, new frequencies and fre-quency coordination; and

(3) Build the replacement system and test it for comparability with the ex-isting 800 MHz system.

(d) Comparable facilities. The replace-ment system provided to an incumbent during an involuntary relocation must be at least equivalent to the existing 800 MHz system with respect to the fol-lowing four factors:

(1) System. System is defined func-tionally from the end user’s point of view (i.e., a system is comprised of base station facilities that operate on an in-tegrated basis to provide service to a common end user, and all mobile units associated with those base stations). A system may include multiple-licensed facilities that share a common switch or are otherwise operated as a unitary system, provided that the end user has the ability to access all such facilities. A system may cover more than one EA if its existing geographic coverage ex-tends beyond the EA borders.

(2) Capacity. To meet the comparable facilities requirement, an EA licensee must relocate the incumbent to facili-ties that provide equivalent channel capacity. We define channel capacity as the same number of channels with the same bandwidth that is currently available to the end user. For example, if an incumbent’s system consists of five 50 kHz (two 25 kHz paired fre-quencies) channels, the replacement system must also have five 50 kHz channels. If a different channel con-figuration is used, it must have the same overall capacity as the original configuration. Comparable channel ca-pacity requires equivalent signaling

capability, baud rate, and access time. In addition, the geographic coverage of the channels must be coextensive with that of the original system.

(3) Quality of service. Comparable fa-cilities must provide the same quality of service as the facilities being re-placed. Quality of service is defined to mean that the end user enjoys the same level of interference protection on the new system as on the old sys-tem. In addition, where voice service is provided, the voice quality on the new system must be equal to the current system. Finally, reliability of service is considered to be integral to defining quality of service. Reliability is the de-gree to which information is trans-ferred accurately within the system. Reliability is a function of equipment failures (e.g., transmitters, feed lines, antennas, receivers, battery back-up power, etc.) and the availability of the frequency channel due to propagation characteristics (e.g., frequency, terrain, atmospheric conditions, radio-fre-quency noise, etc.) For digital data sys-tems, this will be measured by the per-cent of time the bit error rate exceeds the desired value. For analog or digital voice transmissions, this will be meas-ured by the percent of time that audio signal quality meets an established threshold. If analog voice system is re-placed with a digital voice system the resulting frequency response, harmonic distortion, signal-to-noise ratio, and reliability will be considered.

(4) Operating costs. Operating costs are those costs that affect the delivery of services to the end user. If the EA li-censee provides facilities that entail higher operating cost than the incum-bent’s previous system, and the cost in-crease is a direct result of the reloca-tion, the EA licensee must compensate the incumbent for the difference. Costs associated with the relocation process can fall into several categories. First, the incumbent must be compensated for any increased recurring costs asso-ciated with the replacement facilitates (e.g., additional rental payments, in-creased utility fees). Second, increased maintenance costs must be taken into consideration when determining whether operating costs are com-parable. For example, maintenance costs associated with analog systems

may be higher than the costs of digital equipment because manufacturers are producing mostly digital equipment and analog replacement parts can be difficult to find. An EA licensee’s obli-gation to pay increased operating costs will end five years after relocation has occurred.

(e) If an EA licensee cannot provide comparable facilities to an incumbent licensee as defined in this section, the incumbent licensee may continue to operate its system on a primary basis in accordance with the provisions of this rule part.

(f) Cost-sharing plan for 800 MHz SMR EA licensees. EA licensees are required to relocate the existing 800 MHz SMR licensee in these bands if interference to the existing incumbent operations would occur. All EA licensees who ben-efit from the spectrum clearing by other EA licensees must contribute, on a pro rata basis to such relocation costs. EA licensees may satisfy this re-quirement by entering into private cost-sharing agreements or agreeing to terms other than those specified in this section. However, EA licensees are re-quired to reimburse other EA licensees that incur relocation costs and are not parties to the alternative agreement as defined in this section.

(1) Pro rata formula. EA licensees who benefit from the relocation of the in-cumbent must share the relocation costs on a pro rata basis. For purposes of determining whether an EA licensee benefits from the relocation of an in-cumbent, benefitted will be defined as any EA licensee that:

(i) Notifies incumbents operating on frequencies included in their spectrum block of their intention to relocate such incumbents within 90 days of the release of the Public Notice that com-mences the voluntary negotiation pe-riod; or

(ii) Fails to notify incumbents oper-ating on frequencies included in their spectrum block of their intention to re-locate such incumbents within 90 days of the release of the Public Notice that commences the voluntary negotiation period, but subsequently decides to use the frequencies included in their spec-trum block. EA licensees who do not participate in the relocation process

will be prohibited from invoking man-datory negotiations or any of the pro-visions of the Commission’s mandatory relocation guidelines. EA licensees who do not provide notice to the incum-bent, but subsequently decide to use the frequencies in their EA will be re-quired to reimburse, outside of the Commission’s mandatory relocation guidelines, those EA licensees who have established a reimbursement right pursuant to paragraph (f)(3) of this section.

(2) Triggering a reimbursement obliga-tion. An EA licensees reimbursement obligation is triggered by:

(i) Notification (i.e., files a copy of the relocation notice and proof of the incumbent’s receipt of the notice to the Commission within ten days of re-ceipt), to the incumbent within 90 days of the release of the Public Notice com-mencing the voluntary negotiation pe-riod of its intention to relocate the in-cumbent; or

(ii) An EA licensee who does not pro-vide notification within 90 days of the release of the Public Notice com-mencing the voluntary negotiation pe-riod, but subsequently decides to use the channels that were relocated by other EA licensees.

(3) Triggering a reimbursement right. In order for the EA licensee to trigger a reimbursement right, the EA licensee must notify (i.e., files a copy of the re-location notice and proof of the incum-bent’s receipt of the notice to the Com-mission within ten days of receipt), the incumbent of its intention to relocate the incumbent within 90 days of the re-lease of the Public Notice commencing the voluntary negotiation period, and subsequently negotiate and sign a relo-cation agreement with the incumbent. An EA licensee who relocates a channel outside of its licensed EA (i.e., one that is in another frequency block or out-side of its market area), is entitled to pro rata reimbursement from non-noti-fying EA licensees who subsequently exercise their right to the channels based on the following formula:

Ci TcChj

TCh= ×

Ci equals the amount of reimbursement Tc equals the actual cost of relocating the

incumbent

TCh equals the total number of channels that are being relocated

Chj equals the number of channels that each respective EA licensee will benefit from

(4) Payment issues. EA licensees who benefit from the relocation of the in-cumbent will be required to submit their pro rata share of the relocation expense to EA licensees who have trig-gered a reimbursement right and have incurred relocation costs as follows:

(i) For an EA licensee who, within 90 days of the release of the Public Notice announcing the commencement of the voluntary negotiation period, provides notice of its intention to relocate the incumbent, but does not participate or incur relocation costs in the relocation process, will be required to reimburse those EA licensees who have triggered a reimbursement right and have in-curred relocation costs during the relo-cation process, its pro rata share when the channels of the incumbent have been cleared (i.e., the incumbent has been fully relocated and the channels are free and clear).

(ii) For an EA licensee who does not, within 90 days of the release of the Public Notice announcing the com-mencement of the voluntary negotia-tion period, provide notice to the in-cumbent of its intention to relocate and does not incur relocation costs during the relocation process, but sub-sequently decides to use the channels in its EA, will be required to submit its pro rata share payment to those EA li-censees who have triggered a reim-bursement right and have incurred re-location costs during the relocation process prior to commencing testing of its system.

(5) Sunset of reimbursement rights. EA licensees who do not trigger a reim-bursement obligation as set forth in paragraph (f)(2) of this section, shall not be required to reimburse EA licens-ees who have triggered a reimburse-ment right as set forth in paragraph (f)(3) of this section ten (10) years after the voluntary negotiation period be-gins for EA licensees (i.e., ten (10) years after the Commission releases the Pub-lic Notice commencing the voluntary negotiation period).

(6) Resolution of disputes that arise during relocation. Disputes arising out

§ 90.709 Special limitations on amend-ment of applications and on assign-ment or transfer of authorizations licensed under this subpart.

(a) Except as indicated in paragraph (b) of this section, the Commission will not consent to the following:

(1) Any request to amend an applica-tion so as to substitute a new entity as the applicant;

(2) Any application to assign or transfer a license for a Phase I, non-na-tionwide system prior to the comple-tion of construction of facilities; or

(3) Any application to transfer or as-sign a license for a Phase I nationwide system before the licensee has con-structed at least 40 percent of the pro-posed system pursuant to the provi-sions of § 90.725(a) or § 90.725(h), as ap-plicable.

(b) The Commission will grant the applications described in paragrpah (a) of this section if:

(1) the request to amend an applica-tion or to transfer or assign a license does not involve a substantial change in the ownership or control or the ap-plicant; or

(2) The changes in the ownership or control of the applciant are involun-tary due to the original applicant’s in-solvency, bankruptcy, incapacity, or death.

(c) The assignee or transferee of a Phase I nationwide system is subject to the construction benchmarks and re-porting requirements of § 90.725. The as-signee or transferee of a Phase I na-tionwide system is not subject to the entry criteria described in § 90.713.

(d) A licensee may partially assign any authorization in accordance with § 90.1019.

(e) The assignee or transferee of a Phase II system is subject to the provi-sions of §§ 90.1017 and 1.2111(a) of this chapter.

§ 90.711 Processing of Phase II appli-cations.

(a) Phase II applications for author-izations on Channels 166 through 170 and Channels 181 through 185 will be processed on a first-come, first-served basis. When multiple applications are filed on the same day for these fre-quencies in the same geographic area, and insufficient frequencies are avail-able to grant all applications (i.e., if all applications were granted, violation of the station separation provisions of § 90.723(k) of this part would result), these applications will be considered mutually exclusive.

(1) All applications will first be con-sidered to determine whether they are substantially complete and acceptable for filing. If so, they will be assigned a file number and put in pending status. If not, they will be dismissed.

(2) Except as otherwise provided in this section, all applications in pending status will be processed in the order in which they are received, determined by the date on which the application was received by the Commission in its Get-tysburg, Pennsylvania office (or the ad-dress set forth at § 1.1102 of this chapter for applications requiring the fees es-tablished by part 1, subpart G of this chapter).

(3) Each application that is accepted for filing will then be reviewed to de-termine whether it can be granted. Frequencies will be assigned by the Commission pursuant to the provisions of § 90.723.

(4) An application which is dismissed will lose its place in the processing line.

(b) All applications for Channels 161 through 165 that comply with the ap-plicable rules of this part shall be granted. Licensees operating on such channels shall cooperate in the selec-tion and use of frequencies and resolve any instances of interference in accord-ance with the provisions of § 90.173.

(c) Phase II applications for author-ization on all non-Government chan-nels other than Channels 161 through 170 and 181 through 185 shall be proc-essed in accordance with the provisions of subpart W of this part.

§ 90.713 Entry criteria.

(a) As set forth in § 90.717, four 5- channel blocks are available for na-tionwide, commercial use to non-Gov-ernment, Phase I applicants. Appli-cants for these nationwide channel blocks must comply with paragraphs (b), (c), and (d) of this section.

(b)(1) An applicant must include cer-tification that, within ten years of re-ceiving a license, it will construct a minimum of one base station in at least 70 different geographic areas des-ignated in the application; that base stations will be located in a minimum of 28 of the 100 urban areas listed in § 90.741; and that each base station will have all five assigned nationwide chan-nels constructed and placed in oper-ation (regularly interacting with mo-bile and/or portable units).

(2) An applicant must include certifi-cation that it will meet the construc-tion requirements set forth in § 90.725.

(3) An applicant must include a ten- year schedule detailing plans for con-struction of the proposed system.

(4) An applicant must include an itemized estimate of the cost of con-structing 40 percent of the system and operating the system during the first four years of the license term.

(5) An applicant must include proof that the applicant has sufficient finan-cial resources to construct 40 percent of the system and operate the proposed land mobile system for the first four years of the license term; i.e., that the applicant has net current assets suffi-cient to cover estimated costs or a firm financial commitment sufficient to cover estimated costs.

(c) An applicant relying on personal or internal resources for the showing required in paragraph (b) of this sec-tion must submit independently au-dited financial statements certified within one year of the date of the ap-plication showing net current assets sufficient to meet estimated construc-tion and operating costs. An applicant must also submit an unaudited balance sheet, current within 60 days of the date of submission, that clearly shows the continued availability of sufficient net current assets to construct and op-erate the proposed system, and a cer-tification by the applicant or an officer

of the applicant organization attesting to the validity of the balance sheet.

(d) An applicant submitting evidence of a firm financial commitment for the showing required in paragraph (b) of this section must obtain the commit-ment from a bona fide commercially acceptable source, e.g., a state or feder-ally chartered bank or savings and loan institution, other recognized financial institution, the financial arm of a cap-ital equipment supplier, or an invest-ment banking house. If the lender is not a state or federally chartered bank or savings and loan institution, other recognized financial institution, the fi-nancial arm of a capital equipment supplier, or an investment banking house, the lender must also dem-onstrate that it has funds available to cover the total commitments it has made. The lender’s commitment shall contain a statement that the lender:

(1) Has examined the financial condi-tion of the applicant including an au-dited financial statement, and has de-termined that the applicant is credit-worthy;

(2) Has examined the financial viabil-ity of the proposed system for which the applicant intends to use the com-mitment; and

(3) Is willing, if the applicant is seek-ing a Phase I, commercial nationwide license, to provide a sum to the appli-cant sufficient to cover the realistic and prudent estimated costs of con-struction of 40 percent of the system and operation of the system for the first four years of the license term.

(e) A Phase II applicant for author-ization in a geographic area for Chan-nels 166 through 170 in the public safe-ty/mutual aid category may not have any interest in another pending appli-cation in the same geographic area for Channels 166 through 170 in the public safety/mutual aid category, and a Phase II applicant for authorization in a geographic area for channels in the emergency medical category may not have any interest in another pending application in the same geographic area for channels in the emergency medical category.

systems on a primary basis instead of or in addition to its land mobile oper-ations, it must meet the following re-quirements:

(A) A nationwide Phase I licensee must;

(1) Meet its two-year benchmark for the construction of its land mobile sys-tem base stations as prescribed in § 90.725(a); and

(2) Provide a new 10-year schedule, as required in § 90.713(b)(3), for the con-struction of the fixed and/or paging system it intends to construct instead of, or in addition to, its nationwide land mobile system; and

(3) Certify that the financial showings and all other certifications provided in demonstrating its ability to construct and operate its nationwide land mobile system, as required in §§ 90.713 (b), (c) and (d), remain applica-ble to the nationwide system it intends to construct consisting of fixed and/or paging operations on a primary basis instead of, or in addition to, its land mobile operations; or

(4) In lieu of providing the require-ments of paragraph (a)(1)(ii)(A)(3) of this section, provide the financial showings and all other certifications required in §§ 90.713 (b), (c) and (d) to demonstrate its ability to construct and operate a nationwide system con-sisting of fixed and/or paging oper-ations on a primary basis instead of, or in addition to, its land mobile oper-ations.

(B) A non-nationwide Phase I li-censee must first meet the requirement to construct its land mobile base sta-tion and place it in operation, or com-mence service (in accordance with § 90.167) as prescribed in § 90.725(f) or § 90.727, as applicable.

(2) Only by persons who are eligible for facilities under either this subpart or in the pools included in subpart B or C of this part.

(3) Except for licensees classified as CMRS providers under part 20 of this chapter, only for the transmission of messages or signals permitted in the services in which the participants are eligible.

(b) See § 90.720 of this part for permis-sible operations on mutual aid chan-nels.

(c) For operations requiring less than a 4 kHz bandwidth, more than a single emission may be utilized within the au-thorized bandwidth. In such cases, the frequency stability requirements of § 90.213 do not apply, but the out-of- band emission limits of § 90.210(f) must be met.

(d) Licensees, except for licensees au-thorized on Channels 161 through 170 and 181 through 185, may combine any number of their authorized, contiguous channels (including channels derived from multiple authorizations) to form channels wider than 5 kHz.

(e) In combining authorized, contig-uous channels (including channels de-rived from multiple authorizations) to form channels wider than 5 kHz, the emission limits in § 90.210(f) must be met only at the outermost edges of the contiguous channels. Transmitters shall be tested to confirm compliance with this requirement with the trans-mission located as close to the band edges as permitted by the design of the transmitter. The frequency stability requirements in § 90.213 shall apply only to the outermost of the contig-uous channels authorized to the li-censee. However, the frequency sta-bility employed for transmissions oper-ating inside the outermost contiguous channels must be such that the emis-sion limits in § 90.210(f) are met over the temperature and voltage variations prescribed in § 2.995 of this chapter.

(f) A Phase I non-nationwide licensee operating a paging base station, or a fixed station transmitting on fre-quencies in the 220–221 MHz band, may only operate such stations at the co-ordinates of the licensee’s authorized land mobile base station.

(g) The transmissions of a Phase I non-nationwide licensee’s paging base station, or fixed station transmitting on frequencies in the 220–221 MHz band, must meet the requirements of §§ 90.723(d), (g), (h), and (k), and 90.729, and such a station must operate at the effective radiated power and antenna height-above-average-terrain pre-scribed in the licensee’s land mobile base station authorization.

§ 90.735 Station identification. (a) Except for nationwide systems au-

thorized in the 220–222 MHz band, sta-tion identification is required pursuant to § 90.425 of this part.

(b) Trunked systems shall employ an automatic device to transmit the call sign of the base station at 30 minute intervals. The identification shall be made on the lowest frequency in the base station trunked group assigned to the licensee. If this frequency is in use at the time identification is required, the identification may be made at the termination of the communication in progress on this frequency.

(c) Station identification may be by voice or International Morse Code. If the call sign is transmitted in Inter-national Morse Code, it must be at a rate of between 15 to 20 words per minute, and by means of tone modula-tion of the transmitter, with the tone frequency being between 800 and 1000 hertz.

(d) Digital transmissions may also be identified by digital transmission of the station call sign. A licensee that identifies its station in this manner must provide the Commission, upon its request, information (such as digital codes and algorithms) sufficient to de-cipher the data transmission to ascer-tain the call sign transmitted.


§ 90.739 Number of systems authorized in a geographical area.

There is no limit on the number of li-censes that may be authorized to a sin-gle licensee.

[62 FR 46214, Sept. 2, 1997]

§ 90.741 Urban areas for Phase I na-tionwide systems.

Licensees of Phase I nationwide sys-tems must construct base stations, or fixed stations transmitting on fre-quencies in the 220–221 MHz band, in a minimum of 28 of the urban areas list-ed in the following Table within ten years of initial license grant. A base station, or fixed station, is considered to be within one of the listed urban areas if it is within 60 kilometers (37.3 miles) of the specified coordinates (co-ordinates are referenced to North American Datum 1983 (NAD83)).

§ 90.743 Renewal expectancy.

(a) All licensees seeking renewal of their authorizations at the end of their license term must file a renewal appli-cation in accordance with the provi-sions of § 1.949 of this chapter. Licens-ees must demonstrate, in their applica-tion, that:

(1) They have provided ‘‘substantial’’ service during their past license term. ‘‘Substantial’’ service is defined in this rule as service that is sound, favorable, and substantially above a level of me-diocre service that just might mini-mally warrant renewal; and

(2) They have substantially complied with applicable FCC rules, policies, and the Communications Act of 1934, as amended.

(b) In order to establish its right to a renewal expectancy, a renewal appli-cant must submit a showing explaining why it should receive a renewal expect-ancy. At a minimum, this showing must include:

(1) A description of its current serv-ice in terms of geographic coverage and population served;

(2) For an EA, Regional, or nation-wide licensee, an explanation of its record of expansion, including a time-table of the construction of new sta-tions to meet changes in demand for service;

(3) A description of its investments in its system;

(4) Copies of all FCC orders finding the licensee to have violated the Com-munications Act or any FCC rule or policy; and

(5) A list of any pending proceedings that relate to any matter described in this paragraph.

(c) Phase I non-nationwide licensees have license terms of 10 years, and therefore must meet these require-ments 10 years from the date of initial authorization in order to receive a re-newal expectancy. Phase I nationwide licensees and all Phase II licensees

§ 90.745 Phase I licensee service areas.

(a) A Phase I licensee’s service area shall be defined by the predicted 38 dBu service contour of its authorized base station or fixed station transmitting on frequencies in the 220–221 MHz band at its initially authorized location or at the location authorized in accord-ance with §§ 90.751, 90.753, 90.755 and 90.757 if the licensee has sought modi-fication of its license to relocate its initially authorized base station. The Phase I licensee’s predicted 38 dBu service contour is calculated using the F(50,50) field strength chart for Chan-nels 7–13 in § 73.699 (Fig. 10) of this chapter, with a 9 dB correction factor for antenna height differential, and is based on the authorized effective radi-ated power (ERP) and antenna height- above-average-terrain of the licensee’s base station or fixed station. Phase I li-censees are permitted to add, remove, or modify transmitter sites within their existing service area without prior notification to the Commission so long as their predicted 38 dBu service contour is not expanded. The incum-bent licensee must, however, notify the Commission within 30 days of the com-pletion of any changes in technical pa-rameters or additional stations con-structed through a minor modification of its license. Such notification must be made by submitting the appropriate FCC form and must include the appro-priate filing fee, if any. These minor modification applications are not sub-ject to public notice and petition to deny requirements or mutually exclu-sive applications.

(b) Phase I licensees holding author-izations for service areas that are con-tiguous and overlapping may exchange these authorizations for a single li-cense, authorizing operations through-out the contiguous and overlapping service areas. Phase I licensees exer-cising this license exchange option must submit specific information for

each of their external base station sites.

[63 FR 32591, June 12, 1998]

§ 90.751 Minor modifications of Phase I, non-nationwide licenses.

Phase I non-nationwide licensees will be given an opportunity to seek modi-fication of their license to relocate their initially authorized base station, i.e., locate their base station at a site other than its initially authorized loca-tion. The conditions under which modi-fications will be granted and the proce-dures for applying for license modifica-tions are described in §§ 90.753, 90.757 and 1.929 of this chapter. For CMRS li-censees, these modifications will be treated as minor modifications in ac-cordance with § 1.929 of this chapter.

[63 FR 68973, Dec. 14, 1998]

§ 90.753 Conditions of license modifica-tion.

(a) Except as provided in paragraphs (b), and (c) of this section, a Phase I non nationwide licensee may modify its authorization to relocate its au-thorized base station up to one-half the distance over 120 km toward any co- channel licensee’s initially authorized base station, to a maximum distance of 8 km.

(b) A Phase I non-nationwide licensee with an authorized base station located outside a Designated Filing Area (DFA) (see Public Notice, DA 86–173, 52 FR 1302 (January 12, 1987)) may modify its authorization to relocate its author-ized base station up to one-half the dis-tance over 120 km toward any co-chan-nel licensee’s initially authorized base station, to a maximum distance of 25 km, so long as the base station is relo-cated no more than 8 km inside of any DFA (i.e., no more than 8 km from the nearest DFA boundary line).

(c) A Phase I non-nationwide licensee that has been granted Special Tem-porary Authority (STA) to operate at an alternative base station location may modify its authorization to seek permanent authorization at that loca-tion, regardless of whether locating the station at the STA site is in strict con-formance with the provisions of para-graphs (a) and (b) of this section, if the

licensee certifies that such a modifica-tion is in conformance with §§ 90.723 and 90.729 and:

(1) It has constructed its base station and has placed it in operation, or com-menced service, at the STA site on or before January 26, 1996; or

(2) It has taken delivery of its base station transceiver on or before Janu-ary 26, 1996.

(d) The application for a Phase I non- nationwide licensee proposing a base station modification resulting in less than 120 km separation from a co-chan-nel licensee’s initially authorized base station will be accepted by the Com-mission only with the consent of that co-channel licensee, as evidenced in a statement submitted concurrently with the licensee’s application submis-sion on FCC Form 601.

(e) The application of a Phase I non- nationwide licensee proposing a base station modification resulting in at least a 120 km separation from each co- channel licensee’s initially authorized base station but more than one-half the distance over 120 km toward any co-channel licensee’s initially author-ized base station will be accepted by the Commission only with the consent of that co-channel licensee, as evi-denced in a statement submitted con-currently with the licensee’s submis-sion on FCC Form 601.

[61 FR 3845, Feb. 2, 1996, as amended at 63 FR 68973, Dec. 14, 1998]

§ 90.757 Construction requirements. (a) Except as provided in paragraph

(b) of this section, a Phase I non-na-tionwide licensee that is granted modi-fication of its authorization to relocate its base station must construct its base station and place it in operation, or commence service, on all authorized channels on or before August 15, 1996, or within 12 months of initial grant date, whichever is later. The authoriza-tion of a licensee that does not con-struct its base station and place it in operation, or commence service, by this date, cancels automatically and must be returned to the Commission.

(b) A Phase I non-nationwide licensee with a base station authorized at a lo-cation north of Line A must construct its base station and place it in oper-ation, or commence service, on all au-

thorized channels within 12 months of initial grant date, or within 12 months of the date of the release of the terms of an agreement between the United States and Canadian governments on the sharing of 220–222 MHz spectrum between the two countries, whichever is later. The authorization of a licensee that does not construct its base station and place it in operation, or commence service, by this date, cancels automati-cally and must be returned to the Com-mission.

at least 120 km from the land mobile or paging base stations, or fixed stations transmitting on base station transmit frequencies, of co-channel Phase I li-censees, except that separations of less than 120 km shall be considered on a case-by-case basis upon submission by the EA or Regional licensee of:

(A) A technical analysis dem-onstrating at least 10 dB protection to the predicted 38 dBu service contour of the co-channel Phase I licensee, i.e., demonstrating that the predicted 28 dBu interfering contour of the EA or Regional licensee’s base station or fixed station does not overlap the pre-dicted 38 dBu service contour of the co- channel Phase I licensee’s base station or fixed station; or

(B) A written letter from the co- channel Phase I licensee consenting to a separation of less than 120 km, or to less than 10 dB protection to the pre-dicted 38 dBu service contour of the li-censee’s base station or fixed station.

(ii) The Phase I licensee’s predicted 38 dBu service contour referred to in paragraph (a)(1)(i) of this section is cal-culated using the F(50,50) field strength chart for Channels 7–13 in § 73.699 (Fig. 10) of this chapter, with a 9 dB correc-tion factor for antenna height differen-tial, and is based on the licensee’s au-thorized effective radiated power and antenna height-above-average-terrain. The EA or Regional licensee’s pre-dicted 28 dBu interfering contour re-ferred to in paragraph (a)(1)(i) of this section is calculated using the F(50,10) field strength chart for Channels 7–13 in § 73.699 (Fig. 10a) of this chapter, with a 9 dB correction factor for an-tenna height differential.

(2) The licensee complies with the re-quirements of § 90.733(i).

(3) The licensee limits the field strength of its base stations, or fixed stations operating on base station transmit frequencies, in accordance with the provisions of § 90.771.

(4) Upon request by a licensee or the Commission, an EA or regional li-censee shall furnish the technical pa-rameters, location and coordinates of the completion of the addition, re-moval, relocation or modification of any of its facilities within the EA or region. The EA or regional licensee must provide such information within

ten (10) days of receiving written noti-fication.

(c) In the event that the authoriza-tion for a co-channel Phase I base sta-tion, or fixed station transmitting on base station transmit frequencies, within an EA or Regional licensee’s border is terminated or revoked, the EA or Regional licensee’s channel obli-gations to such stations will cease upon deletion of the facility from the Commission’s official licensing records, and the EA or Regional licensee then will be able to construct and operate without regard to the previous author-ization.

[68 FR 43000, July 21, 2003]

§ 90.811 Reduced down payment for li-censes won by small businesses.

Each winning bidder that qualifies as a small business shall make a down payment equal to ten percent of its winning bid (less applicable bidding credits); a winning bidder shall bring its total amount on deposit with the Commission (including upfront pay-ment) to five percent of its net winning bid within five (5) business days after the auction closes, and the remainder of the down payment (five percent) shall be paid within five (5) business days following Public Notice that the Commission is prepared to award the license. The Commission generally will grant the license within ten (10) busi-

ness days after receipt of the remain-der of the down payment.



(a) Eligibility. Parties seeking ap-proval for partitioning and disaggregation shall request an author-ization for partial assignment of a li-cense pursuant to § 1.948 of this chap-ter.

(b) Technical standards—(1) Parti-tioning. In the case of partitioning, re-quests for authorization for partial as-signment of a license must include, as attachments, a description of the parti-tioned service area and a calculation of the population of the partitioned serv-ice area and the licensed geographic service area. The partitioned service area shall be defined by coordinate points at every 3 degrees along the par-titioned service area unless an FCC recognized service area is utilized (i.e., Major Trading Area, Basic Trading Area, Metropolitan Service Area, Rural Service Area or Economic Area) or county lines are followed. The geo-graphic coordinates must be specified in degrees, minutes, and seconds to the nearest second of latitude and lon-gitude and must be based upon the 1927 North American Datum (NAD27). Ap-plicants may supply geographical co-ordinates based on 1983 North Amer-ican Datum (NAD83) in addition to those required (NAD27). In the case where an FCC recognized service area or county lines are utilized, applicants need only list the specific area(s) (through use of FCC designations or county names) that constitute the par-titioned area.

(2) Disaggregation. Spectrum may be disaggregated in any amount.

(3) Combined partitioning and disaggregation. The Commission will consider requests for partial assign-ment of licenses that propose combina-tions of partitioning and disaggregation.

(c) Installment payments—(1) Appor-tioning the balance on installment pay-ment plans. When a winning bidder elects to pay for its license through an installment payment plan pursuant to § 90.812, and partitions its licensed area

or disaggregates spectrum to another party, the outstanding balance owed by the licensee on its installment pay-ment plan (including accrued and un-paid interest) shall be apportioned be-tween the licensee and partitionee or disaggregatee. Both parties will be re-sponsible for paying their propor-tionate share of the outstanding bal-ance to the U.S. Treasury. In the case of partitioning, the balance shall be ap-portioned based upon the ratio of the population of the partitioned area to the population of the entire original li-cense area calculated based upon the most recent census data. In the case of disaggregation, the balance shall be ap-portioned based upon the ratio of the amount of spectrum disaggregated to the amount of spectrum allocated to the licensed area.

(2) Parties not qualified for installment payment plans. (i) The partitionee or disaggregatee shall, as a condition of the approval of the partial assignment application, pay its entire pro rata amount within 30 days of Public Notice conditionally granting the partial as-signment application. Failure to meet this condition will result in a rescis-sion of the grant of the partial assign-ment application.

(ii) The licensee shall be permitted to continue to pay its pro rata share of the outstanding balance and shall re-ceive new financing documents (prom-issory note, security agreement) with a revised payment obligation, based on the remaining amount of time on the original installment payment schedule. These financing documents will replace the licensee’s existing financing docu-ments which shall be marked ‘‘super-seded’’ and returned to the licensee upon receipt of the new financing docu-ments. The original interest rate, es-tablished pursuant to § 1.2110(g)(3)(i) of this chapter at the time of the grant of the initial license in the market, shall continue to be applied to the licensee’s portion of the remaining government obligation. The Commission will re-quire, as a further condition to ap-proval of the partial assignment appli-cation, that the licensee execute and return to the U.S. Treasury the new fi-nancing documents within 30 days of the Public Notice conditionally grant-ing the partial assignment application.

Failure to meet this condition will re-sult in the automatic cancellation of the grant of the partial assignment ap-plication.

(iii) A default on the licensee’s pay-ment obligation will only affect the li-censee’s portion of the market.

(3) Parties qualified for installment pay-ment plans. (i) Where both parties to a partitioning or disaggregation agree-ment qualify for installment payments, the partitionee or disaggregatee will be permitted to make installment pay-ments on its portion of the remaining government obligation, as calculated according to paragraph (d)(1) of this section.

(ii) Each party will be required, as a condition to approval of the partial as-signment application, to execute sepa-rate financing documents (promissory note, security agreement) agreeing to pay their pro rata portion of the bal-ance due (including accrued and unpaid interest) based upon the installment payment terms for which they qualify under the rules. The financing docu-ments must be returned to the U.S. Treasury within thirty (30) days of the Public Notice conditionally granting the partial assignment application. Failure by either party to meet this condition will result in the automatic cancellation of the grant of the partial assignment application. The interest rate, established pursuant to § 1.2110(g)(3)(i) of this chapter at the time of the grant of the initial license in the market, shall continue to be ap-plied to both parties’ portion of the balance due. Each party will receive a license for their portion of the parti-tioned market or disaggregated spec-trum.

(iii) A default on an obligation will only affect that portion of the market area held by the defaulting party.

(iv) Partitionees and disaggregatees that qualify for installment payment plans may elect to pay some of their pro rata portion of the balance due in a lump sum payment to the U.S. Treas-ury and to pay the remaining portion of the balance due pursuant to an in-stallment payment plan.

(d) License term. The license term for a partitioned license area and for

(e) Construction requirements—(1) Re-quirements for partitioning. Parties seek-ing authority to partition must meet one of the following construction re-quirements:

(i) The partitionee may certify that it will satisfy the applicable construc-tion requirements set forth in § 90.665 for the partitioned license area; or

(ii) The original licensee may certify that it has or will meet the construc-tion requirements set forth in § 90.665 for the entire market. In that case, the partitionee must only meet the re-quirements for renewal of its license for the partitioned license area.

(iii) Applications requesting partial assignments of license for partitioning must include a certification by each geographic area 800 MHz SMR licenses in the lower 230 channels will be award-ed to small entities, as that term is de-fined by the SBA.

(iv) Partitionees must submit sup-porting documents showing compliance with the respective construction re-quirements within the appropriate time frames set forth in § 90.665.

(v) Failure by any partitionee to meet its respective performance re-quirements will result in the auto-matic cancellation of the partitioned or disaggregated license without fur-ther Commission action.

(2) Requirements for disaggregation. Parties seeking authority to disaggregate must submit with their partial assignment application a cer-tification signed by both parties stat-ing which of the parties will be respon-sible for meeting the construction re-quirements for the market as set forth in § 90.665. Parties may agree to share responsibility for meeting the con-struction requirements. Parties that accept responsibility for meeting the construction requirements and later fail to do so will be subject to license forfeiture without further Commission action.

(1) The 900 MHz SMR renewal appli-cant involved in a comparative renewal proceeding will receive a renewal ex-pectancy, if its past record for the rel-evant license period demonstrates that:

(i) The renewal applicant has pro-vided ‘‘substantial’’ service during its past license term. ‘‘Substantial’’ serv-ice is defined as service which is sound, favorable, and substantially above a level of mediocre service which just might minimally warrant renewal; and

(ii) The renewal applicant has sub-stantially complied with applicable FCC rules, policies and the Commu-nications Act of 1934, as amended.

(2) In order to establish its right to a renewal expectancy, a 900 MHz renewal applicant involved in a comparative re-newal proceeding must submit a show-ing explaining why it should receive a renewal expectancy. At a minimum, this showing must include:

(i) A description of its current service in terms of geographic coverage and population served;

(ii) An explanation of its record of ex-pansion, including a timetable of the construction of new base sites to meet changes in demand for SMR service;

(iii) A description of its investments in its 900 MHz SMR system; and

(iv) Copies of all FCC orders finding the licensee to have violated the Com-munications Act or any FCC rule or policy; and a list of any pending pro-ceedings that relate to any matter de-scribed in paragraph (b)(2) of this sec-tion.

(3) In making its showing of entitle-ment to a renewal expectancy, a re-newal applicant may claim credit for any system modification applications that were pending on the date it filed its renewal application. Such credit will not be allowed if the modification application is dismissed or denied.

are not eligible to partition their geo-graphic service area or disaggregate their licensed spectrum.

(b) Partitioning. In the case of parti-tioning, applicants and licensees must file FCC Form 603 pursuant to § 1.948 and list the partitioned service area on a schedule to the application. The geo-graphic coordinates must be specified in degrees, minutes, and seconds to the nearest second of latitude and lon-gitude and must be based upon the 1983 North American Datum (NAD83). In the case where an FCC-recognized serv-ice area or county lines are utilized, applicants need only list the specific area(s) through use of FCC designa-tions or county names that constitute the partitioned area.

(c) License term. The license term for a partitioned license area and for disaggregated spectrum shall be the re-mainder of the original licensee’s li-cense term.

(d) Construction requirements. (1) Re-quirements for partitioning. Parties seeking authority to partition must meet one of the following construction requirements:

(i) The partitionee may certify that it will satisfy the applicable construc-tion requirements set forth in §§ 90.767 or 90.769 of this part, as applicable, for the partitioned license area; or

(ii) The original licensee may certify that it has or will meet its five-year construction requirement and will meet the ten-year construction re-quirement, as set forth in §§ 90.767 or 90.769 of this part, as applicable, for the entire license area. In that case, the partitionee must only satisfy the re-quirements for ‘‘substantial service,’’ as set forth in § 90.743(a)(1) of this part, for the partitioned license area by the end of the original ten-year license term of the licensee.

(iii) Failure by any partitionee to meet its respective construction re-quirements will result in the auto-matic cancellation of the partitioned license without further Commission ac-tion (see § 1.946).

(2) Requirements for disaggregation. Parties seeking authority to disaggregate spectrum must certify in FCC Form 601 which of the parties will be responsible for meeting the five- year and ten-year construction require-

ments for the particular market as set forth in § 90.767 or § 90.769, as applicable. Parties may agree to share responsi-bility for meeting the construction re-quirements. If one party accepts re-sponsibility for meeting the construc-tion requirements and later fails to do so, then its license will cancel auto-matically without further Commission action. If both parties accept responsi-bility for meeting the construction re-quirements and later fail to do so, then both their licenses will cancel auto-matically without further Commission action.

§ 90.1207 Licensing. (a) A 4940–4990 MHz band license gives

the licensee authority to operate on any authorized channel in this band within its licensed area of operation. See § 90.1213. A 4940–4990 MHz band li-cense will be issued for the geographic area encompassing the legal jurisdic-tion of the licensee or, in case of a non-governmental organization, the legal jurisdiction of the state or local gov-ernmental entity supporting the non-governmental organization.

(b) Subject to § 90.1209, a 4940–4990 MHz band license gives the licensee au-thority to construct and operate any number of base stations anywhere within the area authorized by the li-cense, except as follows:

(1) A station is required to be individ-ually licensed if:

(i) International agreements require coordination;

(ii) Submission of an environmental assessment is required under § 1.1307 of this chapter; or

(iii) The station would affect areas identified in § 1.924 of this chapter.

(2) Any antenna structure that re-quires notification to the Federal Avia-tion Administration (FAA) must be registered with the Commission prior to construction under § 17.4 of this chapter.

(c) A 4940–4990 MHz band license gives the licensee authority to operate base and mobile units (including portable and handheld units) and operate tem-porary (1 year or less) fixed stations anywhere within the area authorized by the license. Such licensees may op-erate base and mobile units and/or tem-porary fixed stations outside their au-thorized area to assist public safety op-erations with the permission of the ju-risdiction in which the radio station is to be operated. Base and temporary fixed stations are subject to the re-quirements of paragraph (b) of this sec-tion.

(d) Permanent fixed point-to-point and point-to-multipoint stations in the 4940–4990 MHz band must be licensed in-dividually on a site-by-site basis. Such fixed stations that connect 4940–4990 MHz band base and mobile stations that are used to deliver broadband service, as well as other public safety networks using spectrum designated

for broadband use, are accorded pri-mary status. Primary status is also ac-corded to stand-alone permanent fixed 4940–4990 MHz band links that are used to deliver broadband service. Primary permanent fixed point-to-point and point-to-multipoint stations must use directional antennas with gains greater than 9 dBi up to 26 dBi. Permanent fixed point-to-point stations that do not meet the criteria for primary sta-tus will be authorized only on a sec-ondary, non-interference basis to base, mobile, temporary fixed, and primary permanent fixed operations.

§ 90.1209 Policies governing the use of the 4940–4990 MHz band.

(a) Channels in this band are avail-able on a shared basis only and will not be assigned for the exclusive use of any licensee.

(b) All licensees shall cooperate in the selection and use of channels in order to reduce interference and make the most effective use of the authorized facilities. Licensees of stations suf-fering or causing harmful interference are expected to cooperate and resolve this problem by mutually satisfactory arrangements. If licensees are unable to do so, the Commission may impose restrictions including specifying the transmitter power, antenna height, or area or hours of operation of the sta-tions concerned. Further, the Commis-sion may prohibit the use of any 4.9 GHz channel under a system license at a given geographical location when, in the judgment of the Commission, its use in that location is not in the public interest.

(c) Licensees will make every prac-tical effort to protect radio astronomy operations as specified in § 2.106, foot-note US311 of this chapter.

(d) There is no time limit for which base and temporary fixed stations au-thorized under a 4940–4990 MHz band li-cense must be placed in operation. Fixed point-to-point stations which are licensed on a site-by-site basis must be placed in operation within 18 months of the grant date or the authorization for that station cancels automatically.

§ 90.1215 Power limits. The transmitting power of stations

operating in the 4940–4990 MHz band must not exceed the maximum limits in this section.

Channel bandwidth (MHz)

Low power maximum conducted

output power (dBm)

(2) High power devices are also lim-ited to a peak power spectral density of 21 dBm per one MHz. High power de-vices using channel bandwidths other than those listed above are permitted; however, they are limited to peak power spectral density of 21 dBm/MHz. If transmitting antennas of directional gain greater than 9 dBi are used, both the maximum conducted output power and the peak power spectral density should be reduced by the amount in decibels that the directional gain of the antenna exceeds 9 dBi. However, high power point-to-point and point-to- multipoint operations (both fixed and temporary-fixed rapid deployment) may employ transmitting antennas with directional gain up to 26 dBi with-out any corresponding reduction in the maximum conducted output power or spectral density. Corresponding reduc-tion in the maximum conducted output

power and peak power spectral density should be the amount in decibels that the directional gain of the antenna ex-ceeds 26 dBi.

(b) Low power devices are also lim-ited to a peak power spectral density of 8 dBm per one MHz. Low power devices using channel bandwidths other than those listed above are permitted; how-ever, they are limited to a peak power spectral density of 8 dBm/MHz. If transmitting antennas of directional gain greater than 9 dBi are used, both the maximum conducted output power and the peak power spectral density should be reduced by the amount in decibels that the directional gain of the antenna exceeds 9 dBi.

(c) The maximum conducted output power is measured as a conducted emis-sion over any interval of continuous transmission using instrumentation calibrated in terms of an RMS-equiva-lent voltage. If the device cannot be connected directly, alternative tech-niques acceptable to the Commission may be used. The measurement results shall be properly adjusted for any in-strument limitations, such as detector response times, limited resolution bandwidth capability when compared to the emission bandwidth, sensitivity, etc., so as to obtain a true maximum conducted output power measurement conforming to the definitions in this paragraph for the emission in question.

(d) The peak power spectral density is measured as conducted emission by direct connection of a calibrated test instrument to the equipment under test. If the device cannot be connected directly, alternative techniques accept-able to the Commission may be used. Measurements are made over a band-width of one MHz or the 26 dB emission bandwidth of the device, whichever is less. A resolution bandwidth less than the measurement bandwidth can be used, provided that the measured power is integrated to show total power over the measurement band-width. If the resolution bandwidth is approximately equal to the measure-ment bandwidth, and much less than the emission bandwidth of the equip-ment under test, the measured results shall be corrected to account for any difference between the resolution band-

width of the test instrument and its ac-tual noise bandwidth.

(e) The ratio of the peak excursion of the modulation envelope (measured using a peak hold function) to the max-imum conducted output power shall not exceed 13 dB across any 1 MHz bandwidth or the emission bandwidth whichever is less.

47 CFR Ch. I (10–1–10 Edition) § 90.1305

§ 90.1305 Permissible operations. Use of the 3650–3700 MHz band must

be consistent with the allocations for this band as set forth in part 2 of the Commission’s Rules. All stations oper-ating in this band must employ a con-tention-based protocol (as defined in § 90.7).

§ 90.1307 Licensing. The 3650–3700 MHz band is licensed on

the basis of non-exclusive nationwide licenses. Non-exclusive nationwide li-censes will serve as a prerequisite for registering individual fixed and base stations. A licensee cannot operate a fixed or base station before registering it under its license and licensees must delete registrations for unused fixed and base stations.

§ 90.1309 Regulatory status. Licensees are permitted to provide

services on a non-common carrier and/ or on a common carrier basis. A li-censee may render any kind of commu-nications service consistent with the regulatory status in its license and with the Commission’s rules applicable to that service.

§ 90.1311 License term. The license term is ten years, begin-

ning on the date of the initial author-ization (non-exclusive nationwide li-cense) grant. Registering fixed and base stations will not change the over-all renewal period of the license.

§ 90.1312 Assignment and transfer. Licensees may assign or transfer

their non-exclusive nationwide li-censes, and any fixed or base stations registered under those licenses will re-main associated with those licenses.

§ 90.1319 Policies governing the use of the 3650–3700 MHz band.

(a) Channels in this band are avail-able on a shared basis only and will not be assigned for the exclusive use of any licensee.

(b) Any base, fixed, or mobile station operating in the band must employ a contention-based protocol.

(c) Equipment incorporating an unre-stricted contention-based protocol (i.e. one capable of avoiding co-frequency

interference with devices using all other types of contention-based proto-cols) may operate throughout the 50 megahertz of this frequency band. Equipment incorporating a restricted contention-based protocol (i.e. one that does not qualify as unrestricted) may operate in, and shall only tune over, the lower 25 megahertz of this fre-quency band.

(d) All applicants and licensees shall cooperate in the selection and use of frequencies in the 3650–3700 MHz band in order to minimize the potential for interference and make the most effec-tive use of the authorized facilities. A database identifying the locations of registered stations will be available at http://wireless.fcc.gov/uls. Licensees should examine this database before seeking station authorization, and make every effort to ensure that their fixed and base stations operate at a lo-cation, and with technical parameters, that will minimize the potential to cause and receive interference. Licens-ees of stations suffering or causing harmful interference are expected to cooperate and resolve this problem by mutually satisfactory arrangements.

[72 FR 40722, July 25, 2007]

§ 90.1321 Power and antenna limits. (a) Base and fixed stations are lim-

ited to 25 watts/25 MHz equivalent isotropically radiated power (EIRP). In any event, the peak EIRP power den-sity shall not exceed 1 Watt in any one- megahertz slice of spectrum.

(b) In addition to the provisions in paragraph (a) of this section, transmit-ters operating in the 3650–3700 MHz band that emit multiple directional beams, simultaneously or sequentially, for the purpose of directing signals to individual receivers or to groups of re-ceivers provided the emissions comply with the following:

(1) Different information must be transmitted to each receiver.

(2) If the transmitter employs an an-tenna system that emits multiple di-rectional beams but does not emit mul-tiple directional beams simulta-neously, the total output power con-ducted to the array or arrays that com-prise the device, i.e., the sum of the power supplied to all antennas, an-tenna elements, staves, etc. and

summed across all carriers or fre-quency channels, shall not exceed the limit specified in paragraph (a) of this section, as applicable. The directional antenna gain shall be computed as fol-lows:

(i) The directional gain, in dBi, shall be calculated as the sum of 10 log (number of array elements or staves) plus the directional gain, in dBi, of the individual element or stave having the highest gain.

(ii) A lower value for the directional gain than that calculated in paragraph (b)(2)(i) of this section will be accepted if sufficient evidence is presented, e.g., due to shading of the array or coher-ence loss in the beam-forming.

(3) If a transmitter employs an an-tenna that operates simultaneously on multiple directional beams using the same or different frequency channels and if transmitted beams overlap, the power shall be reduced to ensure that the aggregate power from the overlap-ping beams does not exceed the limit specified in paragraph (b)(2) of this sec-tion. In addition, the aggregate power transmitted simultaneously on all beams shall not exceed the limit speci-fied in paragraph (b)(2) of this section by more than 8 dB.

(4) Transmitters that emit a single directional beam shall operate under the provisions of paragraph (b)(2) of this section.

(c) Mobile and portable stations are limited to 1 watt/25 MHz EIRP. In any event, the peak EIRP density shall not exceed 40 milliwatts in any one-mega-hertz slice of spectrum.

§ 90.1323 Emission limits. (a) The power of any emission outside

a licensee’s frequency band(s) of oper-ation shall be attenuated below the transmitter power (P) within the li-censed band(s) of operation, measured in watts, by at least 43 + 10 log (P) dB. Compliance with this provision is based on the use of measurement instrumen-tation employing a resolution band-width of 1 MHz or less, but at least one percent of the emission bandwidth of the fundamental emission of the trans-mitter, provided the measured energy is integrated over a 1 MHz bandwidth.

(b) When an emission outside of the authorized bandwidth causes harmful

interference, the Commission may, at its discretion, require greater attenu-ation than specified in this section.

§ 90.1331 Restrictions on the operation of base and fixed stations.

(a)(1) Except as provided in para-graph (a)(2) of this section, base and fixed stations may not be located with-in 150 km of any grandfathered sat-ellite earth station operating in the 3650–3700 MHz band. The coordinates of these stations are available at http:// www.fcc.gov/ib/sd/3650/.

(2) Base and fixed stations may be lo-cated within 150 km of a grandfathered satellite earth station provided that the licensee of the satellite earth sta-tion and the 3650–3700 MHz licensee mu-tually agree on such operation.

(3) Any negotiations to enable base or fixed station operations closer than 150 km to grandfathered satellite earth stations must be conducted in good faith by all parties.

(b) (1) Except as specified in para-graph (b)(2) of this section, base and fixed stations may not be located with-in 80 km of the following Federal Gov-ernment radiolocation facilities: St. Inigoes, MD—38° 10′ N., 76°, 23′ W. Pascagoula, MS—30° 22′ N., 88°, 29′ W. Pensacola, FL—30° 21′ 28″ N., 87°, 16′ 26″

§ 90.1415 Establishment, execution, and application of the network sharing agreement.

The following requirements and proc-esses relate to the establishment, exe-cution, and application of the NSA:

(a) Approval of NSA as pre-condition for granting the Upper 700 MHz D Block License. The Public Safety Broadband Licensee must negotiate an NSA and such other agreements as the Commis-sion may require or allow with the win-

ning bidder for the Upper 700 MHz D Block license. The NSA and related agreements or documents must be ap-proved by the Commission and then ex-ecuted by the relevant parties. Parties to the NSA must also include the Upper 700 MHz D Block licensee, the Network Assets Holder, and the Oper-ating Company, as these entities are defined in § 90.7.

(b) Requirement of negotiation. Nego-tiation of an NSA between the winning bidder for the Upper 700 MHz D Block license and the Public Safety Broadband Licensee must commence by the date the winning bidder files its long form application or the date on which the Commission designates the Public Safety Broadband Licensee, whichever is later, and must conclude within six months of that date. Parties to this negotiation are required to ne-gotiate in good faith. Two members of the Commission staff, one from the Wireless Telecommunications Bureau and one from the Public Safety and Homeland Security Bureau, shall be present at all stages of the negotiation as neutral observers.

(c) Reporting requirements. Beginning three months from the triggering of the six-month negotiation period, the Public Safety Broadband Licensee and the winning bidder for the Upper 700 MHz D Block license must jointly pro-vide detailed reports, on a monthly basis and subject to a request for con-fidential treatment, on the progress of the negotiations throughout the re-mainder of the negotiations. These re-ports must include descriptions of all material issues that the parties have yet to resolve.

(d) Submission of final agreement. As soon as the parties have reached an agreement on all the terms of the NSA, related agreements or documents, and such other agreements as the Commis-sion may require or allow but not later than five business days after the six- month period for negotiation has ex-pired, they must submit the NSA to-gether with all agreements and related documents referenced in the NSA, for review and approval by the full Com-mission. The Commission will act on the NSA within 60 days of receipt. The Commission may approve the NSA in

its entirety, approve with modifica-tions, or require the parties to address additional terms or re-draft existing terms within a specified timeframe. After the NSA is approved, the parties must execute the NSA and such other agreements as the Commission may re-quire or allow and submit executed copies to the Commission within 10 business days of approval.

(e) Submission of disputed issues. If the parties have not reached agreement on all terms of the NSA and related agree-ments by the end of the six-month pe-riod, they must notify the Commission not later than five business days after the expiration of the six-month period of the terms on which they have agreed, the nature of the remaining issues, each party’s position on each issue, whether additional negotiation is likely to produce an agreement, and, if so, a proposed deadline for reaching agreement on the NSA. Authority is delegated jointly to the Chiefs of the Wireless Telecommunications Bureau and the Public Safety and Homeland Security Bureau to resolve any remain-ing disputes.

(f) Resolution of disputes. Actions to resolve disputes may include, but are not limited to:

(1) Granting additional time for nego-tiation;

(2) Issuing a decision on the disputed issues and requiring the submission of a draft agreement consistent with the decision;

(3) Directing the parties to further brief the remaining issues in full for immediate Commission decision; and/ or

(4) Immediate denial of the long-form application filed by the winning bidder for the Upper 700 MHz D Block license.

(g) Default by winning bidder for Upper 700 MHz D Block license. If the winning bidder for the Upper 700 MHz D Block fails to comply with negotiation or dis-pute resolution requirements or fails to execute a Commission-approved NSA, its long form application will be de-nied. If the long form application of the winning bidder of the Upper 700 MHz D Block license is denied for any reason, including as a consequence of an action taken pursuant to paragraphs (e) and (f) of this section, it will be deemed to have defaulted under § 1.2109(c) of this

chapter and will be liable for the de-fault payment specified in § 1.2104(g) of this chapter.

§ 90.1420 Failure to comply with the NSA or the Commission’s rules.

(a) Failure to comply with the Com-mission’s rules or the terms of the NSA may warrant cancelling the Public Safety Broadband License. The poten-tial remedies also include, but are not limited to, assigning the license to an-other entity, directing the Public Safe-ty Broadband Licensee to transfer the assignable right to purchase the assets at fair market value, ordering specific performance, or ordering removal and replacement of individual officers, di-rectors or member organizations of the Public Safety Broadband Licensee.

(b) If the Commission cancels or ter-minates the Upper 700 MHz D Block li-cense, a fair market valuation of the shared wireless broadband network as-sets shall be performed immediately, pursuant to the fair market valuation methodology set forth in the NSA. In the event that the Upper 700 MHz D Block license is awarded to a new enti-ty, the Public Safety Broadband Li-censee’s option to purchase the net-work and all network assets if and whenever the Upper 700 MHz D Block license is cancelled or terminated and its right of first refusal to purchase the network assets if and whenever such assets are otherwise to be sold shall be assigned to the new Upper 700 MHz D Block licensee and the new Network Assets Holder.

§ 90.1425 Resolution of disputes after grant of the upper 700 MHz D block license.

(a) The Public Safety Broadband Li-censee, the Operating Company, the Network Assets Holder, and the Upper 700 MHz D Block licensee may at any time bring a complaint to the Commis-sion based on a claim that another party to the NSA has deviated from the terms of the NSA, or a petition for a declaratory ruling to resolve the prop-er interpretation of an NSA term or provision.

(b) The Commission shall have pri-mary responsibility and jurisdiction for adjudicating disputes that arise fol-lowing execution of the NSA. The Com-mission may, however, require the par-ties to first seek a settlement to the dispute or authorize the parties to re-solve the dispute through litigation or other means. Breach of license terms, the NSA, or the Commission’s rules may result in cancellation of the Pub-lic Safety Broadband License, the Upper 700 MHz D Block license, or both.

(c) The Chiefs of the Public Safety and Homeland Security Bureau and the Wireless Telecommunications Bureau are delegated joint responsibility for adjudicating disputes.

§ 90.1430 Local public safety build-out and operation.

(a) The Upper 700 MHz D Block li-censee and the Operating Company through its lease arrangements shall, except in the two limited cir-cumstances set forth herein, have the exclusive right to build and operate the Shared Wireless Broadband Network.

(b) Rights to early build-out in areas with a build-out commitment. In an area where the Upper 700 MHz D Block li-censee has committed, in the NSA, to build out by a certain date, a public safety entity may, with the pre-ap-proval of the Public Safety Broadband Licensee and subject to the require-ments set forth herein, construct a broadband network in that area at its own expense so long as the network is capable of operating on the Shared Wireless Broadband Network and meets all the requirements and specifications of the network required under the NSA.

(1) Options for early build-out in areas with a build-out commitment. In order to obtain authorization to construct a broadband network as set forth in paragraph (b) of this section, the re-questing public safety entity must agree to one of the following:

(i) To, on its own, or through the Public Safety Broadband Licensee act-ing on its behalf, construct the net-work at its own expense, and upon completion of construction, transfer the network to the Upper 700 MHz D Block licensee, which shall then inte-

grate that network into the Shared Wireless Broadband Network con-structed pursuant to the NSA; or

(ii) To, in agreement with the Upper 700 MHz D Block licensee, provide all funds necessary for the Upper 700 MHz D Block licensee to complete the early construction of the network, including any and all additional resource and personnel costs, allowing the Upper 700 MHz D Block licensee at all times to own, operate, and manage the network as an integrated part of the Shared Wireless Broadband Network.

(2) Negotiation of amendment to NSA. Under either early build out option set forth in paragraph (b)(1) of this section, the Public Safety Broadband Licensee, the Upper 700 MHz D Block licensee, and the public safety entity must, prior to any construction, negotiate an amendment to the NSA regarding this part of the network, specifying owner-ship rights, fees, and other terms, which may be distinct from the analo-gous terms governing the Shared Wire-less Broadband Network, and such amendment must be approved by the Commission.

(i) Such amendment must provide the terms under which the Upper 700 MHz D Block licensee shall receive full own-ership rights and shall compensate the public safety entity (or the Public Safety Broadband Licensee, where ap-propriate) for the construction of the network; and shall, absent agreement to the contrary, provide for such trans-fer and compensation to occur prior to the scheduled build out date for such network in the NSA.

(ii) Any right to compensation from the Upper 700 MHz D Block licensee re-lated to such early build-out shall be limited to the cost that would have been incurred had the Upper 700 MHz D Block licensee constructed the network itself in accordance with the original terms and specifications of the NSA, as reasonably determined by the parties and negotiated as part of the required NSA amendment required in paragraph (b)(2) of this section. Such costs shall not include costs attributable solely to advancing the date of construction or otherwise expediting the construction process.

(3) Operations. The public safety enti-ty may not commence operations on

the network until ownership of the net-work has been transferred to the Upper 700 MHz D Block licensee. Further, no operations shall be allowed except those authorized and conducted pursu-ant to the authority of the Public Safe-ty Broadband Licensee.

(4) Attribution of early build-out to na-tional benchmarks. Upon completion of construction, transfer of ownership to the Upper 700 MHz D Block licensee, and compensation as required herein, if applicable, the Upper 700 MHz D Block licensee may include the network con-structed pursuant to the early build- out provisions herein for purposes of determining whether it has met its na-tional build-out benchmarks and the build-out requirements of the NSA.

(5) Rights to build out and operate in areas without a build-out commitment. In areas for which the NSA does not re-quire the Upper 700 MHz D Block li-censee to build out the Shared Wireless Broadband Network, a public safety en-tity may build out and operate a sepa-rate, exclusive network in the 700 MHz public safety broadband spectrum at any time, provided the public safety entity has received the written ap-proval of the Public Safety Broadband Licensee and operates its independent network pursuant to a spectrum leas-ing arrangement into which the public safety entity has entered with the Pub-lic Safety Broadband Licensee.

(i) Such leasing arrangement shall not require the approval or consent of the Upper 700 MHz D Block licensee; however, the Public Safety Broadband Licensee must provide the Upper 700 MHz D Block licensee with notice of the public safety entity’s intent to con-struct in that area within 30 days of re-ceipt of a request from a public safety entity seeking to exercise this option, and shall inform the Upper 700 MHz D Block licensee of the public safety en-tity’s anticipated build-out date(s).

(ii) Should the Upper 700 MHz D Block licensee, within 30 calendar days from receipt of notice of the public safety entity’s intent to construct in that area, certify in writing to the Public Safety Broadband Licensee that it will build out the shared network in the area within a reasonable time of the anticipated build-out date(s), as de-termined by the Public Safety

Broadband Licensee, the Public Safety Broadband Licensee shall not allow the public safety entity to build and oper-ate its own separate exclusive network in that area, provided that the Upper 700 MHz D Block licensee and the Pub-lic Safety Broadband Licensee execute an amendment to the NSA indicating the Upper 700 MHz D Block licensee’s commitment to build the network in that area. Such commitment shall be-come enforceable against the Upper 700 MHz D Block licensee as part of its overall build-out requirements.

(iii) If the Upper 700 MHz D Block li-censee does not exercise its option to commit to build out the network in the requested area within 30 calendar days of receipt of notice of the public safety entity’s intent to construct in such area, the Public Safety Broadband Li-censee and the public safety entity may proceed with a spectrum leasing arrangement, which must be filed with and approved by the Commission prior to the public safety entity commencing any operations. The spectrum leasing arrangement must take the form of a spectrum manager leasing arrange-ment under the rules specified in § 1.9020 of this chapter, and incorporate the following conditions:

(A) The network must provide broadband operations;

(B) The network must be fully inter-operable with the Shared Wireless Broadband Network;

(C) The network must be available for use by any public safety entity in the area;

(D) The network must satisfy any other terms or conditions required by the Public Safety Broadband Licensee; and

(E) The public safety entity must construct and place into operation its network within one year of the effec-tive date of the spectrum manager leasing arrangement. If the public safe-ty entity fails to place the network into operation within one year, the Public Safety Broadband Licensee shall terminate the spectrum leasing arrangement pursuant to § 1.9020(h)(3) of this chapter. The public safety enti-ty may also seek extended implemen-tation authority from the Commission pursuant to the requirements of § 90.629.

(6) Except as set forth herein, the separate network is not required to meet the other specifications of the Shared Wireless Broadband Network. Absent agreement of the public safety entity, the Public Safety Broadband Licensee, and the Upper 700 MHz D Block licensee, the separate network may not operate using any spectrum associated with the Upper 700 MHz D Block license.

(7) The Public Safety Broadband Li-censee must file with the Commission any spectrum manager leasing arrange-ment as specified in § 1.9020(e) of this chapter; such filing shall identify the public safety entity leasing the spec-trum, the particular areas of spectrum leased as part of this build-out option, and the specific network infrastructure and equipment deployed on such leased spectrum.

§ 90.1432 Conditions for waiver to allow limited and temporary wide-band operations in the 700 MHz public safety spectrum.

(a) Wideband operations in the 700 MHz Public Safety spectrum. Wideband oper-ations are prohibited in the public safe-ty allocation of the 700 MHz band pub-lic safety spectrum except where the Commission has granted a waiver pur-suant to §§ 1.3 and 1.925 of this chapter and subject to the additional condi-tions and requirements specified in this section. Grants of waiver are restricted to the deployment of a wideband sys-tem in the consolidated narrowband portion or the internal public safety guard band portion of the public safety broadband spectrum. Where spectrum in the narrowband segment or internal guard band segment is unavailable for wideband operations, public safety en-tities may request a waiver to operate in the upper 1.25 megahertz of the pub-lic safety broadband spectrum.

(b) Any public safety entity seeking to conduct wideband operations within the public safety allocation must file a request for waiver that is accompanied by an application for authorization and includes the following information:

(1) A letter from the Public Safety Broadband Licensee, confirming that the proposed wideband deployment is not inconsistent with the broadband

deployment plan for the affected or ad-jacent service areas; and

(2) A description of the conditions or transition requirements, if any, agreed to between the applicant and the Pub-lic Safety Broadband Licensee.

(c) Additional requirement for wideband operations in the narrowband segment and Internal Guard Band. If an appli-cant seeks permission to deploy wide-band systems in the narrowband seg-ment, its waiver request must also in-clude a letter from the appropriate re-gional planning committee or state li-censee confirming that the proposed wideband deployment will not disrupt any regional or state planning efforts that are underway.

(d) Additional requirements and condi-tions for wideband operations in the broadband segment. Permission to con-duct wideband operations in the broadband segment will be granted only where spectrum in the narrowband segment or the internal guard band is unavailable for wideband operations. In no event will permission be granted to conduct wideband oper-ations in geographic areas scheduled for broadband deployment within the first three years of the build-out plan for the Shared Wireless Broadband Net-work.

(1) An applicant seeking permission to deploy wideband systems in the broadband segment must have first issued a request for proposal (RFP) that permitted interested parties to submit broadband proposals that are technically consistent with the Shared Wireless Broadband Network.

(2) A request for waiver that seeks permission to deploy wideband systems in the broadband segment must include the following information:

(i) A substantially supported, de-tailed technical showing dem-onstrating that insufficient spectrum in the narrowband segment or the in-ternal guard band is available to sup-port the desired wideband operations;

(ii) A showing that rejected responses to the required broadband network RFP were more costly, provided less coverage as measured by throughput at the network edge, or were otherwise in-ferior to the accepted wideband pro-posal; and

This plan must specify how and by what date the wideband applicant will integrate its proposed wideband system into Shared Wireless Broadband Network and must include a certification that the public safety entity will not seek reimburse-ment for any costs involved in con-verting the wideband system to Shared Wireless Broadband Network upon completion of that network in the ap-plicant’s geographic area.

(3) Authority to conduct wideband operations in the broadband segment of the public safety spectrum will be sub-ject to the following conditions:

(i) All devices operating on the wide-band system must be designed to inter-operate with Shared Wireless Broadband Network;

(ii) All waivers will expire automati-cally upon the Upper 700 MHz D Block licensee’s initiation of service in the service area covered by such waiver.

(e) Secondary status of wideband oper-ations. All wideband operations per-mitted under this section shall be sec-ondary to the authorized narrowband or broadband applications, as applica-ble.

(f) License terms for wideband oper-ations. Any secondary license to con-duct wideband operations in the public safety spectrum shall have a term of no more than five years.

(g) Renewal of wideband authorization. Any request for renewal of an initial authorization to conduct wideband op-erations shall be filed not less than 180 days prior to expiration of the license. All renewal requests must include a showing that continued operation of the wideband system is in the public interest and must be accompanied by a letter from the Public Safety Broadband Licensee confirming that continuing wideband operations are not inconsistent with the broadband deployment plan for the affected or ad-jacent service areas. The license term for any renewal of a license granted under the waiver provisions herein shall not exceed three years. No more than one license renewal will be grant-ed.

(h) Grandfathered wideband STA oper-ations. Upon request, the Public Safety

and Homeland Security Bureau may grant a public safety entity that has constructed, deployed, and was oper-ating a wideband system as of July 31, 2007 pursuant to STA to extend the STA grant for periods of no more than 180 days until, but not later than, six months following the selection of the Public Safety Broadband Licensee.

§ 90.1435 Prohibition on discontinu-ance of public safety operations.

The Upper 700 MHz D Block licensee, the Operating Company, and the Net-work Assets Holder are prohibited from discontinuing or degrading the broadband network service provided to the Public Safety Broadband Licensee or to public safety entities unless ei-ther at the request of the entity or en-tities in question or it has first ob-tained the approval of the Commission. The Upper 700 MHz D Block licensee shall notify the affected public safety entity or entities and the Public Safety Broadband Licensee at least 30 days prior to any unrequested discontinu-ance or degradation of network service.

§ 90.1440 Reporting obligations.

(a) The Upper 700 MHz D Block li-censee and the Public Safety Broadband Licensee shall jointly file quarterly reports with the Commis-sion. These reports shall include au-dited financial statements, how the specific requirements of public safety are being met, detailed information on the areas where broadband service has been deployed, which public safety en-tities are using the broadband network in each area of operation, what types of applications are in use in each area of operation, and the number of declared emergencies in each area of operation.

(b) The Public Safety Broadband Li-censee and the Upper 700 MHz D Block licensee have joint responsibility to register the base station locations with the Commission, providing basic tech-nical information, including geo-graphic location.
